Computer Vision notes by: Eyal Amir
 

Summary: Computer Vision
notes by: Eyal Amir
March 20, 1997
Abstract
This is a summary of the Vision topic, taken mostly from [Nal93]. It
is therefore restricted to passive vision (we might take care of that soon),
and to ignorance of domain­specific knowledge (we may take care of that
using [Bin82]).
