CN730: Models of Visual Perception

Spring 2011

Prerequisites : Consent of the instructors, Ennio Mingolla and Arash Yazdanbakhsh

Office hours: by appointment

The 2011 edition of this course offers an advanced survey of selected topics of current interest in the neural and computational modeling of mammalian vision. This year's topics include brain imaging, visual search, brightness perception, and cortical anatomy. Some classes will be held at laboratories of nearby institutions. Students are expected to have a sufficient interdisciplinary grounding in the fundamentals of computational modeling of mammalian vision to read primary research sources extensively. A term project that combines a problem statement, literature review, and either (1) simulation of a model or (2) a design for a psychophysical experiment is required.
