Abstract

From the point of view of vector spaces, intensity invariant pattern recognition corresponds to identifying vectors independently of their length, which means that such methods consist primarily on measuring angles between vectors in vector spaces. We describe a few such methods that have proven to be efficient for various intensity variations of targets in unsegmented natural scenes. The conventional wisdom for camouflage states that the best camouflage is one that breaks up the lines of objects, so most camouflage schemes are binary. We discuss the best methods of detecting such camouflage objects in natural scenes.
