The Main Cognitive Model of Visual Recognition: Contour Recognition

In this paper, we will study the following pattern recognition problem: Every pattern is a 3-dimensional graph, its surface can be split up into some regions, every region is composed of the pixels with the approximately same colour value and the approximately same depth value that is distance to eyes, and there may also be some contours, e.g., literal contours, on a surface of every pattern. For this problem we reveal the inherent laws. Moreover, we establish a cognitive model to reflect the essential characteristics of the recognition of this type of patterns. In [1], a coarser model or a basicer one is described. In this paper, some important errors are revised, some key things are added, at last, a complete model is described.
