Filter bank is on the left side.
Two template correlators are on the right side. . It begins with the study of some fundamental properties of these networks such as their dynamic behavior. Although the book contains rigorous mathematical material, it also contains some important applications of these two nets in biology, signal and information processing. Local diffusion of information between neighboring cells as well as a global propagation through the entire array are investigated. In the 2D case, a pattern categorization is provided using the notion of stable and unstable modes.
