John Tsotsos is a Canadian Computer Scientist whose research spans the fields of Computer Vision, Human Vision, Robotics, and Artificial Intelligence. He is best known for his work in visual attention, specifically for establishing the need for visual attention in both biological and computational systems through an argument based on the computational complexity of visual information processing[1] and subsequently developing a computational framework for visual attention known as the Selective Tuning model[2]. He is also acknowledged as a pioneer in the area of Active Vision, his students and he being first to propose strategies for active object recognition and object visual search by a robot[3][4]. He has made many contributions to machine vision (particularly motion interpretation, colour processing, binocular vision, active robotic head design[5], shape analysis[6] as well as to human vision[7][8][9][10], robotics[11] and applied areas such as cardiology or dentistry[12][13][14] and assistive robotics[15].

Education

John Tsotsos received his Honours BASc in Engineering Science (1974), MSc in Computer Science (1976) and Ph.D. in Computer Science (1980), all from the University of Toronto with John Mylopoulos as the primary supervisor throughout. For his doctorate research, he developed the first computer system to interpret visual motion depicted in digital image sequences, with application to heart motion analysis. That work led to a postdoctoral fellowship in Cardiology, funded by the Ontario Heart Foundation at Toronto General Hospital, and supervised by the unit's Chief, Dr. E. Douglas Wigle.

Academic Career

Tsotsos first taught computer science at Atkinson College, York University, in 1978-79. On completing his Ph.D., he joined the University of Toronto on faculty in both Departments of Computer Science and of Medicine. In 1980 he founded the highly respected Computer Vision Group at the University of Toronto, which he led for 20 years. He received a Canadian Heart Foundation Scholarship for the years 1981-84. During the years at the University of Toronto, he was named a Fellow of the Canadian Institute for Advanced Research (CIFAR) (1985-90) and awarded a CP-Unitel Fellowship (1990-95) in CIFAR's Artificial Intelligence, Robotics and Society Program[16].

He was recruited to move to York University in 2000 as Director of the Centre for Vision Research. Under his directorship, the centre was ranked in the top six interdisciplinary vision research organizations in the world. At York, he was awarded the NSERC Tier I Canada Research Chair[17] in Computational Vision which he has held for three consecutive terms (2003-2024). In 2014, he founded York's Centre for Innovation in Computing at Lassonde[18] (IC@L) which he led during 2014-present. Other appointments include: Adjunct Professorships in Computer Science and in Ophthalmology and Vision Sciences at the University of Toronto (2000 - present); Visiting Professor University of Hamburg, Germany, 1981; Visiting Professor, Polytechnical University of Crete, Greece 1992; Adjunct Professor, Dept. of Computer Science, University of Western Ontario, 2001 - 2002; Faculty Fellow, Centre for Advanced Studies, IBM Canada, Toronto Labs, 2002 - 2003; Visiting Professor, INRIA Sophia-Antipolis, NeuroMathComp Laboratory, France, 2007; Adjunct Scientist, Toronto, Rehab Institute, University of Toronto, 2011 - 2013; Visiting Professor, Brain and Cognitive Sciences, MIT, 2014.

Tsotsos has served on several journal editorial boards (Computer Vision and Image Understanding, Image and Vision Computing, AI and Medicine, Cognitive Processing, Vision Research) and almost 100 conference organizing and program committees. Notably, he was General Chair of the 7th IEEE International Conference on Computer Vision[19].

He co-edited a 2005 comprehensive reference book titled Neurobiology of Attention[20] with Laurent Itti and Geraint Rees. His first research monograph was published in 2011 by MIT Press, A Computational Perspective on Visual Attention[21]. He has also been a co-editor of several other collections of research papers.

On May 12, 2018, Konstantinos Derpanis, Gregory Dudek and Michael Jenkin organized a day-long Verbal Festschrift to celebrate his 65th birthday. The proceedings were recorded and the talks and photographs are publicly available[22].

Honours, Awards and Distinctions

He has received many additional awards and honours including several best paper awards, among them a 1987 inaugural Marr Prize citation, the 1997 CITO Innovation Award for Leadership in Product Development from the Ontario Centres of Excellence (shared with W.J.

Iakovos, the father of Nikolaos, held a Doctorate of Law from the University of Padua and served as President of the Primary Council and Advocate General of the Ionian Islands[32]. On Mar. 14, 1821, he was invested in the Knights Commanders of the Order of St. Michael and St. George[33][34]. Iakovos' uncle Georgios Chalikiopoulos Mantzaros, (and Tsotsos' 7th-degree uncle), was the 304th (and last) Protopappas of the Greek Orthodox Church on Corfu (1975-1799)[35] and the first Archbishop of Corfu. Alexandros S. Kokotos was Tsotsos' 3rd-degree uncle, and he was one of the godparents of Prince Philip, Duke of Edinburgh.
