Brian Wandell – Professor, Stanford University
An introduction to vision science and its applications to imaging technologies. The course is designed specifically for students interested in various aspects of imaging technologies. The course consists of a series of lectures, seminar discussions, and laboratory tutorials. Lectures given by Professor Wandell will cover the basic tools used in digital imaging and image quality measurement; software simulations of digital imaging will be a significant component of the course; guests from industry will provide special seminars and give their perspectives on industry directions.
