Course Meeting Times
Lectures: 1 session / week, 1.5 hours / session
Overview
An advanced seminar on issues of current interest in human and machine vision. Topics vary from year to year. This year, the class will involve studying the perception of materials. A topic and a set of readings will be chosen each week, and a participant will be in charge of leading discussion. Topics will be tackled from multiple standpoints, including optics, psychophysics, computer graphics and computer vision. Exact topics will be determined by the participants.
Material Appearance: Physical, Perceptual and Computational Issues
Physics
- The interaction of light and matter
- How material surfaces are formed and deformed
Human perception
- Lightness, color, and transparency
- Gloss, texture, and other complex properties
Computer vision
- Texture analysis and synthesis
- Separation of illumination and reflectance
Computer graphics
- Simple parametric models for reflectance
- Image based rendering of materials
- Weathering and distressing
Specific materials
- Skin and hair
- Food
Requirements
