CS 213: Visual Perception

Instructor: Aditi Majumder (Office: DBH 4056)
Timings: MW 11:00am-12:20pm

Quarter: Spring 2013

Course Description

This course will serve as an introduction to the process of visual perception. The goal of this course is to provide the student with a understanding of what goes on behind of scenes of human visual perception, and how this understanding can help to advance the technologies of computer vision, computer graphics, multimedia and human computer interaction (HCI).
This course will offer both the physiological and the psychophysical approach to understand human vision and will relate the two fields together to create a consistent and complete understanding of the process of visual perception. For the physiological approach, the course will introduce the areas of lower level visual processing in the receptors of the eye and the lateral geniculate nucleus and higher level visual processing in different areas of the brain. In the psychophysical approach, the course will introduce the different psychophysical models of human vision, like the models of perceptual organization, perceptual segregation, and construction. Concepts of color, depth, movement and their visual perception will be introduced. To relate the materials presented in the context of different areas of computer science, examples of the quantification and use of these physiological and psychophysical models in computer vision, computer graphics, multimedia and HCI will be referenced.
