Computer Vision
• The study of how computers can be
programmed to extract useful information
about the environment from optical images
– The common problems studied in computer
vision are based on decompositions of visual
perception
– However, in theory, the visual perception may
not be decomposed intrinsically
• In other words, the decompositions do not provide a
good model
