The History of the Institute of Computer Graphics and Vision (ICG) 1992-2024

With Observations on the Evolution of Computer Vision & Computer Graphics
Franz Leberl, Professor Emeritus

The Institute’s history was first assembled at the time of its 20th anniversary in 2012. A few edits followed since then. Buried in the detail are a few milestones worth highlighting:

Our evolution towards Visual Computing.
The institute’s involvement in the creation of the study programs for Software Engineering and Management as well as Informatics / Computer Science.
Our 2 START awardees, the 3 promotions under the auspices of the President of the Republic, our entrepreneurs and Horst Bischof serving as our University’s Vice-President for Research.
The growth from a single 1992-professorship to a total of 7 professors by 2020, a most remarkable reflection of the growing importance of the field of visual computing.

FROM 1811 TO 1992: RUN-UP TO A NEW INSTITUTE

Graz University of Technology started in 1811 as a polytechnical institute. Classes kicked off in December with Lorenz von Vest as professor of Chemistry and Botany. The School was sponsored and presided by Archduke John.

Habsburg Archduke John [Erzherzog Johann] started the origins of Graz University of Technology in 1811, when he was a mere 29 years old.

Computer Science is the most recent academic endeavor to be included in the University’s offerings. The Institute for Numerical Mathematics had been offering classes in computing to students of Applied Mathematics since the late 1960’s. A new institute was dedicated to Information Processing with the 1977-arrival of Prof. Hermann Maurer. It was an extension of the team in Applied Mathematics within the School of Applied Science [Technisch-Naturwissenschaftliche Fakultät].

In 1977, Prof. Hermann Maurer was the initial professor of computer science [Informationsverarbeitung], and orchestrated the development of the University’s computer science organisation and study programs.

The University’s degree programs did not include computer science. Efforts in the late 1970’s and early 1980’s to establish Computer Science failed. Then, universities in Austria were subordinated agencies of the Ministry of Science, centrally managed by Ministry staff in Vienna. In their view, Computer Science programs should be limited to Vienna and Linz. Therefore, Graz defined a novel alternative program entitled “Telematics” — combining Electrical Engineering and Computer Science. Ministry staff considered this to be sufficiently different from Computer Science and approved the program for a 1985-kick-off.

Telematics was a roaring success with high enrollment numbers. More professors were needed. Ministerial approval was achieved for the creation of three new professorships and associated institutes. One was the Institute for Computer Graphics and Vision.

By 1992 there were 5 professors of computer science, each heading his own institute. Prof. Posch was appointed in 1984 to the 2nd chair, followed by Lucas, Maas and Leberl in 1991/1992 (All portraits taken from austria-forum.org)

THE INSTITUTE’S INCEPTION

One new professorship was to address Computer-Aided Design [CAD]. The position was assigned to the Institute for Geometry within Applied Mathematics. However, the 1988-candidate-search was broadened to “Computer-Aided Geometry and Graphics”. The competition was won by Franz Leberl. As was typical at that time, an 1989-negotiation was at the Viennese Ministry, not at the University. This resulted in the agreement that Franz Leberl start on 1st of October 1992, and that a new Institute would then be approved. During the 3 intervening years until 1992, the Ministry funded visiting professors to bridge the transition to the dedicated new professorship.

Organization

1-Oct-1992 saw a new Institute for “Computerunterstützte Geometrie und Grafik” within the School of Applied Science at Graz University of Technology. This was translated into “Institute for Computer Graphics and Vision” and thereby broadened that focus to “vision”.

Kick-Off-Day

1-Oct-1992 was a Thursday and the inaugural day of the new professor. A 3-hour class on Computer Graphics was attended by ~ 300 students of Telematics and of Applied Mathematics with a specialization in “Information Processing”.

Staffing and equipment budget

The 1989-negotiation with Ministry staff in Vienna had resulted in an exceptional budget for 4 University Assistants, 1 administrator and 1 engineer, and equipment worth € 0.9 million.

The initial team

By the 1st of January 1993 all 6 positions were filled with 3 recent graduates of Telematics (Konrad Karner, Raimund Seywald, Margrit Gelautz) and with Michael Gruber (photogrammetry and several years of practical work experience, for example at Joanneum Research in Graz). Margrit Gelautz had previously earned a Magister degree in Mathematics from Graz University, and followed this up with a Dipl.-Ing. degree in Telematics. Andrea Zunegg was the administrator. The IT-infrastructure was in the hands of Dietmar Eggbauer, followed in December 1994 by Andreas Wurm (a graduate of a technical high school with a diploma in electrical engineering). Konrad Karner and Raimund Seywald focussed on Computer Graphics, Margrit Gelautz and Michael Gruber on Computer Vision.

COMPUTER VISION | COMPUTER GRAPHICS | VISUAL COMPUTING

The Institute’s development was inspired by the unparalleled growth in the importance of visual data. Bill Gates called the period 1998–2008 the “First Digital Decennium” with its increase in PC installations, cell phone penetration, broadband accessibility and the advent of the digital image.

Note that the CCD (as the heart of many digital cameras) was not invented until 1969. The Nobel-prize was awarded at the end of this 1st digital decade, in 2009, to the CCD-inventors George Smith and Willard Boyle at the AT&T laboratories.

Bill Gate’s idea would see us currently [in 2019] at the start of a third digital decennium. Considering the appearance of 1 Terabyte USB-sticks, 4 µm pixels, near-zero sensor costs and Graphical Processing Units (GPUs) one may argue that digital infrastructure constraints to the processing of visual data have evaporated.

Miniaturization and cost reduction in combination with smart phones, personal assistants and wearable computing have converted the once exotic ideas for mixed and augmented reality to mainstream topics of research and to innovative commercial activities.

The Institute’s evolution builds on these dramatic changes in the digital World. Annual research contracts grew from initially € 300,000 to € 3.3 million in 2011. That level was maintained during recent years.

Annually about 4 major international conferences on Computer Vision take place, each of these motivating many thousand scientists to travel worldwide. Additionally, there are regional as well as national conferences and workshops. Augmented, Mixed and Virtual Reality conferences such as the annual conference by ACM-SIGGRAPH attract more than 30,000 attendees.

Bill Gates presented the keynote address to the 2008 Las Vegas CES trade show. This was his farewell-speech from the software industry. In this speech, he defined the “first digital decade 1998-2008”.

“Computer Graphics” has its roots in computer science and was an extension of applied mathematics with its long tradition in geometry and geometric algorithms. In Computer Science, the topic initially led a fringe existence. Today, however, there hardly is an academic computing team without a strong graphics group.

“Computer Vision” was first associated with sensors and electronic hardware. Its original home was in electrical engineering and was called “Image Processing”. Computer Scientists initially had an interest in “patterns”, be those in languages, data bases or pixel arrangements. A globally small community developed in what was called “Pattern Recognition”. This changed towards the end of the 1980s when mainstream computer science discovered imagery and pixel processing as an application of mathematical and algorithmic concepts. Pattern Recognition and Image Processing morphed into “Computer Vision”. With the vast talent pool in computing, the masses of motivated students, the emerging software industry and the growing access to research funds, Computer Vision and Computer Graphics developed explosively.

The Institute’s kick-off in 1992 rode that wave. However, Computer Graphics and Computer Vision were seen at the time as profoundly and internationally separated fields. It was a special opportunity for Graz that a new Institute could avoid the separation of the fields. While there may have been separate scientific communities, conferences, journals and books, there also exists a joint tool kit of methods and concepts for both Computer Vision and Graphics. In 1992 ours may have been one of the very few academic teams globally where Graphics and Vision were combined.

Today a joint view of vision and graphics has become a global trend under the name “Visual Computing”. And the advent of Augmented Reality greatly benefitted from a tight link between those fields: here, Vision and Graphics feed off one another.

THE FIRST DECADE 1992 - 2002

New professors introduce themselves to the entire University by a public inaugural speech [“Antrittsvorlesung”] for all University staff as well as family and friends. This was in early 1993. The image below is a memento from that event.

After the inaugural lecture in the early 1993 the then president of the university, Prof. H. Kahlert (standing next to Franz Leberl), consults with the owner of Anton-Paar GmbH, Ulrich Santner (with his back to the camera), and Prof. Cerjak, professor of mechanical engineering (left).

In 1995 we organized a 3rd anniversary via an Open House. One of the attendees was the university’s president Hartmuth Kahlert (professor of physics) who expressed his surprise about the level of activity with the question: “Is this all for real or just a Potemkin’s Village”? It was for real.

The Ministry staff concerned themselves with structuring the university into Schools and Institutes. They noticed that in Graz there existed an Institute for Geometry as well as an Institute for Computer-Aided Geometry in the same School of Applied Science. The Ministry concluded that these Institutes should merge.

We changed the name to “Maschinelles Sehen und Darstellen” and the merger debate was off the table.

The Institute’s original home was rental space at Münzgrabenstrasse 11 in Graz. This image shows the professorial office in the building’s attic.

After 7 years in the rental space, new buildings had been erected specifically for the growing number of computer science institutes in the University campus Inffeldgasse.

We changed the name to “Maschinelles Sehen und Darstellen” and the merger debate was off the table.

On the Institute’s 20th anniversary, we had counted 34 visiting scientists. Some spent a full semester or even more, and they enriched life at our Institute. The following singles out those who have spent a semester or more with us.

MICHAEL GERVAUTZ VIENNA UNIVERSITY OF TECHNOLOGY | 1995-6

The Technisch-Naturwissenschaftliche Fakultaet (School of Applied Science) offered a sigificant budget to fund visiting professors. The first and very important visitor was Michael Gervautz in 1995/6. This was from an a.o.Prof.-position at Vienna Technical University’s Institute of Computer Graphics. Michael revamped the Computer Graphics courses and stimulated research in this area. He later left his academic career, started a business and successfully sold it to Qualcomm. This morphed into globally operating, 6000 employee PTC (Parametric Technology GmbH) where he now holds a senior management position.

AXEL PINZ VIENNA UNIVERSITY OF TECHNOLOGY | 1995-1999

By 1995, Axel Pinz started a multi-year visit under an arrangement with Prof. Walter Kropatsch’s Pattern Recognition group at Vienna University of Technology. In Graz, he submitted and successfully defended his Habilitation thesis which resulted in his perpetual affiliation with the institute. He greatly affected the courses in Computer Vision. The Graz habilitation, in combination with his tenured position at Vienna, provided him with the title of a.o. Prof. The visit ended in 1999 when he won a full time tenured position as a.o. Prof. at the School of Electrical Engineering in Graz.

GERVAUTZ & PINZ –> STUDIERSTUBE | 1996

In 1996 Gervautz and Pinz defined a project entitled “Studierstube” and with the Austrian Science Fund FWF they developed an innovative augmented reality infrastructure which is still in use to this day. Michael Gervautz’s Viennese harvest of doctoral candidates surrounding the Studierstube-project included Dieter Schmalstieg.

MILAN SONKA UNIVERSITY OF IOWA | 1999

Prof. Milan Sonka from University of Iowa’s Department of Electrical and Computer Engineeringoriginates from Prague. He chose our Institute in Graz for a full year sabbatical visit in 1999. This resulted in a large cooperative “Virtual Liver Project”. In ensuing years, staff from Graz visited Iowa multiple times, several doctoral theses were completed and medical augmented reality became a celebrated achievement. Reinhard Beichel not only was one of the successful doctoral graduates from this initiative, but he also won a faculty position at the University of Iowa.

ANDREJ FERKO COMENIUS UNIVERSITY BRATISLAVA | 2001-2004

Fully 3 years, from 2001 through 2004, Prof. Andrej Ferko from Comenius University in Bratislava (Slovakia) was visiting to augment courses and teaching work in geometry and computer graphics.

HORST BISCHOF | 2000-2003

Initially, Horst Bischof joined the Institute as a “Visiting Professor” in 2000. More on the Bischof-development follows.

After 4 years the original 4 University Assistants had graduated with their doctorates in 1996, and left the university. A second generation of University Assistants took over: Stefan Scherer (physics), Regine Bolter, Heinz Mayer and Markus Grabner (Telematik). Their contracts again were for 4-years, to end in 2000.

FIRST A LEBERL LEAVE OF ABSENCE

The period 1996 – 1999 was marked by a 40-months leave of absence of Franz Leberl to assume the position of CEO of Austria’s national research center in Seibersdorf near Vienna, today renamed the Austrian Institute of Technology AIT. Axel Pinz admirably ran day-to-day matters of research and teaching. Formal leadership was with Reinhard Posch, professor and leader of his own Institute.

THE NEED FOR A FRESH START

Leberl’s 40-months-leave-of-absence ended in the fall of 1999. At that time it became evident that none of the then-existing University Assistants wanted to pursue an academic carreer in Graz. It became abundantly clear that the Insitute needed a fresh start with new people, almost like in 1992.

LACK OF CONTINUITY

An Austrian University institute’s classical structure is with a single Professor assisted by a few pre-doctoral assistants. By 1999 this had revealed itself as a bad model in a highly dynamic environment like Computer Science. Continuity was provided only by one lonely professor, the administrator and the technical support person. Discontinuity ruled in research, teaching and technology transfer. Do we really want to restart the cycle every 4 years?

CHANGING THE INSTITUTE’S STRUCTURE

The solution was a change in the Institute’s structure. Have 3 permanent professorships at the expense of assistantships. And trust that assistantships, be they pre- or post-doctoral, would be funded from competitively acquired soft money (research grants and research contracts).

Some creative budgeting was needed to accomplish this change. The immediate need was met with the budget for visiting professors.

TWO MULTI-YEAR POSITIONS FOR VISITING PROFESSORS

The University’s people accepted the proposals and during the year 2001 two temporary visiting professorships could be funded . One position for Computer Vision was taken by Horst Bischof, visiting for 4 years from Vienna University of Technology. A second position for Computer Graphics was filled with Andrej Ferko, visiting for 3 yars from Comenius University, Bratislava. This temporary arrangement carried the Institute through its 10th anniversary in 2002 and ended in 2004.

The Ministry of Science staff continued to reject a Computer Science degree program in Graz. In its place they suggested a program for “Information Management”. They believed that this should result in a business degree (Bak. rer. soc. oec. and Mag. rer. soc. oec.).

The Institute became deeply involved in the creation of a degree program under ministerial rules for “Information Management“, but [we tricked and] created an engineering program as close to Computer Science as possible. We called it “Software Development and Knowledge Management“. The Ministry approved the result, the initial enrollment exceeded all predictions. This created the need for a new professorship and Institute for Knowledge Management.

While Telematics was a program with shared responsibility between Electrical Engineering and Computer Science, the new program was the first to be entirely “owned“ by Computer Science.

Along the way, the program was renamed into Software Engineering and Management and the degrees were changed into BSc and Dipl.-Ing. [MSc.]

A PERFORMANCE REVIEW | 2002

The research projects and affiliations with research sponsors, the teaching work, the publications record, the number of master and doctoral graduates have been documented in a brochure that appeared at the occasion of the Institute’s 10th anniversary. It offers 51 pages about the first decade of the Institute.

The personnel and budgets during the start-up decade of the Institute are contained in that same brochure, but also in the material compiled for the 20th anniversary (see further down).

A 10TH ANNIVERSITY CELEBRATION | 2002

An event was organized with Prof. Milan Sonka from the University of Iowa giving an inspirational talk about medical vision and graphics in the 1888-imperially impressive auditorium of the University. The talk was attended by many University VIPs, and was succeeded by a buffet and an open house at the Institute.

THE SECOND DECADE 2002 - 2012

It was a 2003-breakthrough when approval was granted to advertize two additional full and permanent professorships at the Institute. The position for Computer Vision was won by Horst Bischof He abandoned his tenured a.o. (außerordentliche) Professorship at Vienna University of Technology and started in Graz on the 31^st of December 2003.

The second professorship for Virtual Reality was won by Dieter Schmalstieg, former doctoral candidate under funding from the Studierstube-project invented by Michael Gervautz and Axel Pinz. Dieter Schmalstieg’s transfer was also from a tenured position as an a.o.Prof. at Vienna University of Technology, and was on the 1st of October 2004. He had just won a large START research grant (at the time the second such grant ever awarded in Computer Science). He brought this grant and a significant team of researchers to Graz.

Our Institute benefitted greatly from talents provided by Vienna University of Technology. Gervautz-Pinz-Bischof-Schmalstieg all came from there. Inversely, only Margrit Gelautz moved in the opposite direction and became a professor in Vienna, after learning to be a scientist at our institute.

By 2004, Universities no longer were subordinated offices of the Ministry of Science. They became independent entities under their own management. Professors no longer were federal civil servants, but employees of their University.

Graz University of Technology was free to give itself a structure to its liking. A new School of Computer Science [Fakultät für Informatik] with 8 Institutes came into existence. Ours became one of 8 Institutes in the new School, then the only one with 3 professors, the largest number of doctoral candidates, the greatest publications record and soft money budget. Today, the School is the Fakultät für Informatik und biomedizinische Technik.

Freedom existed now for academic programs without ministerial approval. Horst Bischof championed the setup of an uncompromising Computer Science program and served as the Dean of Students. From its 2006-start it now is a true success story.

It was a surprise to Franz Leberl to receive the honor of a 25-year service party after a mere 16 years since the Institute’s start. The government added Franz Leberl’s 1968-year in military service and the initial 8 years at the University from 1976 to 1984 (then as a.o. Professor of Photogrammetry). Leaves of absence were counted as “service”. The anniversary offered a party and an extra salary.

More creative accounting made it possible to attract Gerhard Reitmayr into a 4^th professorship on the 1^st of June 2009. He had spent 5 post-doctoral years at Cambridge University on cutting edge research in Augmented Reality. As a doctoral graduate of Dieter Schmalstieg in Vienna, he was a “grandchild” of the Gervautz-Pinz project Studierstube. His professorship focused on “Mobile Augmented Reality“. This topic was the essence of a new Christian-Doppler-Laboratory with a staff of 14 people.

Prof. Reitmayr built the Institute’s group on mobile augmented reality in the period 2009 to 2013.

The 20^th anniversary of the Institute’s inception motivated the creation of a summary of activities and successes in teaching and research. The two essential summaries are (1) a 2012-assembly of key performance numbers and (2) a 2014-list of all completed and pending doctoral projects.

The anniversary was recognized by a talk on Visual Computing by Professor Luc van Gool from the Swiss Federal Institute of Technology. This was acompanied by an Open Lab Day with a full program of presentations.

From the 1992-start with 7-people, great things had been achieved by 2012. Please look at these summary numbers:

By 2012, the Institute had accumulated 94 completed doctoral projects and had matured to an annual average of 8 fresh doctoral graduates. Overall, the Institute had developed to a peak with grant and contract research funds at nearly EUR 3 million, publications at more than 140 per year, employment at 65 positions and more than 30 doctoral candidates simultaneously working on their research.

	Total	Annual average
	1992-2012	2007-2012
Cooperators	191	65
Publications	1352	144
Diploma- & Master’s Theses	208	15
Disserations	94	8
Grants / Contract Research	€ 20.3 Mio	€ 2.8 Mio
Awards / Distinctions	50	5.6

Horst Bischof was appointed to the 4-year position of the Vice-President for Research [Vize-Rektor Forschung] of the University in 2011, and in 2019 started his 3rd 4-year term. This reflects on Prof. Bischof’s scientific achievements and skills as a research manager. He makes the Institute’s staff proud, but also affects the evolution of the Institute.

To compensate for Prof. Bischof ‘s split focus on University affairs, a new tenure track position [Laufbahnstelle] was advertised and was won by Thomas Pock. He assumed that position during the 20^th anniversary year 2012. Upon completion of his habilitation, Tom Pock would advance automatically to a tenured Associate Professorship. However, things developed differently, as will be described below.

MOVING THROUGH THE THIRD DECADE

The 3^rd decennium started with Franz Leberl’s status change into Professor Emeritus on the 1^st of October 2013. A formal send-off was organized (see the 4-page announcement and program). Photos from the event can be seen in this gallery.

As he thanked everyone for this farewell event Franz Leberl had this to say:

In 1992 I was “young” at an age of 47 years. The team spirit in the new Institute inspired awe. We were friends, not just co-workers.

By now I have become the beneficiary of senior discounts. And yet magic keeps the Institute youthful. The Institute’s leadership has power and is set to maintain visual computing excellence. So, at this time of farewell I am truly happy about the Institute and confident about its future.

I sense that I achieved success as stated in my 1993-inaugural speech: “Success is when I have become superfluous”.
Thank you!

In 2013 the number of professors dropped to two: Bischof – Schmalstieg. .Not only did Franz Leberl change into an Emeritus, but also Gerhard Reitmayr left for a career in industry. By the way, Prof. Reitmayr had won a professorial offer to move to the University of Innsbruck, while Graz was also ready to such an offer. But he declined tboth offers in favor of a career in industry. He currently works at Qualcomm in San Diego (USA) as head of a team for Augmented Reality innovation.

To fill the Reitmayr-vacancy, a term-unlimited full professorship for Mobile Augmented Reality was advertized and won by Vincent Lepetit from France, then coming to Graz from the prestigious Swiss Federal Institute in Lausanne (EPFL, Switzerland). The position is now titled Computer Vision for Augmented Reality.

Prof. Vincent Lepetit joined the Institute on the 1st of February 2014 to continue the development of Mobile Augmented Reality. Vincent Lepetit currently splits his time between his position in Graz and a professorship at the Laboratoire Bordelais de Recherche en Informatique at the Université de Bordeaux (France).

Soft money arrived from the Austrian Institute of Technology [AIT] to fund a term-limited 5-year professorship on “Mobile Vision“. This was won by Tom Pock, thereby abandoning his tenure track position (see above). Since the 1st of June 2014, Tom Pock augments the three professors Bischof-Schmalstieg-Lepetit by a 4th professorship. The abandoned Laufbahnstelle was advertized and won by Fritz Fraundorfer who transferred from Munich Technical University back to Graz.

Since then, a new term-unlimited tenured full professorship was created in Vision, Learning and Optimization. Tom Pock won that position. His previously held soft-money term-limited professorship was essentially “upgraded”.

Prof. Tom Pock assumed his professorship on the 1st of June 2014 to advance the field of Mobile Vision.

The current 3^rd decennium of the Institute will see the development of 3 additional professorships by way of tenure track associate professorships (so-called “Laufbahnstellen”). These tenure track positions have been advertized and have been won by

Fritz Fraundorfer: 3D vision, vision for robotics, camera drones
Denis Kalkofen: Situated visualization for augmented reality
Markus Steinberger: High performance graphics

Upon completion of their respective habilitation processes, each of these assistant professors will earn the right to award doctorates (the “venia legendi”) and will be fully tenured with the title of “Associate Proessor”. They will bring the number of professors at the Institute to 7.

Three tenure track positions are being held by Assistant Professors Fraundorfer, Kalkofen, Steinberger

CELEBRATING 30 YEARS OF ICG GRAZ UNIVERSITY OF TECHNOLOGY

The ICG [Institute for Computer Vision and Graphics] at Graz University of Technology started on 1 October 1992 as the home of a new professorship for Computergestützte Geometrie und Graphik, awarded to Franz Leberl. The initial director of the Institute, Franz Leberl, was followed by Horst Bischof until his ascent to the Vice-Presidency for Research of the University. Then, Dieter Schmalstieg led the Institute until his transfer to a prestigious Alexander-von-Humboldt-professorship in Stuttgart. Prof. Tom Pock assumed the leadership of the Institute and organized the anniversary celebration, held on the 12^th of June 2023.

The celebration continued with a series of science talks by graduates from the ICG who achieved academic and business successes. Five talks were given by graduates who have become university professors, one talk was by a serial entrepreneur. Since there were only 6 slots for those talks, other great scientific achievements had to remain unrecognized.

The celebration ended with catered food, a jazz trio led by Franz Leberl and augmented by singing Tom Pock. Everyone enjoyed several hours of interactions among people who may not have seen one another for extended periods.

The President of Graz University of Technology, Prof. Harald Kainz, opens the day-long celebration of 30 years since the creation of the Institute of ComputerVision and Graphics in the Aula of the University under the statue of Emperor Franz-Joseph I whom personally opened the Aula in 1888.

Opening remarks were offered by the Dean of the School of Computer Science and Biomedical Engineering, Prof. Roderick Bloem [„School“ is „Faculty“]

The director of the ICG and organizer of the anniversary celebration, Tom Pock contributed to the opening remarks with a review of the Institute’s history and performance numbers.

The celebration’s opening statements concluded with a few anecdotes by the Institute’s founder, Franz Leberl. He explained the German- and English-language names of the ICG and their genesis. He also speculated about the reasons for the Institute’s successes.
