ICAL Professor John Tsotsos Leads Team of Scientists Disproving 60-year-old Theory
A team led by John Tsotsos, professor in the Department of Electrical Engineering and Computer Science at the Lassonde School of Engineering, found that the human brain does not select interesting portions of an image to process preferentially, as the highly influential 1958 theory of Donald Broadbent proposed.
“Our study looks at this for vision and tests the leading algorithms that compute the saliency measure and asks the question ‘are those algorithms performing at the same level as humans do on these images’? For example, if the task is to determine if there is a cat in a scene, does the saliency algorithm pick out the cat correctly? The study showed that these algorithms are far from doing as well as humans,” said Tsotsos.
