Camouflage and visual perception.
How does an animal conceal itself from visual detection by other animals? This review paper seeks to identify general principles that may apply in this broad area. It considers mechanisms of visual encoding, of grouping and object encoding, and of search. In most cases, the evidence base comes from studies of humans or species whose vision approximates to that of humans. The effort is hampered ...
متن کاملConvexity-Based Visual Camouflage Breaking
Camouflage is frequently used by animals and humans (usually for military purposes) in order to conceal objects from visual surveillance or inspection. Most camouflage methods are based on superpositioning multiple edges on the object that is supposed to be hidden, such that its familiar contours and texture are masked. In this work, we present an operator, (Darg), that is applied directly to t...

A Model for Visual Camouflage Breaking
Some animals use counter-shading in order to prevent their detection by predators. Counter-shading means that the albedo of the animal is such that its image has a flat intensity function rather than a convex intensity function. This implies that there might exist predators who can detect 3D objects based on the convexity of the intensity function. In this paper, we suggest a mathematical model...
