Tsotsos, John - Mathematics and Computer Sciences - York University
John Tsotsos is Canada’s premiere interdisciplinary vision scientist. His research addresses how the human brain processes what the eyes see as well as how to use that knowledge to develop innovative robotic systems that can see and understand the visual world in the performance of complex tasks. One of his major achievements is to define the Selective Tuning theory of vision: it has inspired new discoveries regarding the function of the human visual system as well as a new autonomous, intelligent, wheelchair for the physically challenged. His leadership in Canada is second to none, having built world-class vision groups and networks, and leading major scientific activities internationally in both computer and human vision science.

Tsotsos, John - Mathematics and Computer Sciences - York University
John Tsotsos is Canada’s premiere interdisciplinary vision scientist, spanning computer and human vision. An international leader in active vision and computational models of vision and attention, he provided the first formal theorems regarding the complexity of human vision. Using these, he defined a neural architecture and theory of human visual attention, including counterintuitive predictions. These predictions have been strongly supported experimentally, now forming a new basis for vision science. His leadership in Canada is second to none, having built world-class vision groups and networks, and leading major scientific activities internationally in both computer and human vision science.
