Modelling the visual cortex with "Modulo system" concept.

"Modulo system" is a general information extracting and processing network for modelling the nervous system. Its essential features are briefly summarized. The concept is applied to visual pattern recognition. The input is a two-dimensional picture of an object. The network extracts the contours, the line-segments, the lines of different directions, and the vertices of different numbers of lines, in successive functional layers. Afterwards, it recognized the simplest known pattern which has the actually extracted features. Uncertainty, association, and tolerance are also concerned. The network is detailed for the classification of of three-dimensional geometrical objects.
