Abstract

PURPOSE: To attain high-speed discrimination and also to provide the simplification of unit constitution and the reduction in cost, by extracting the feature values of a graphic pattern in an easy method and then by discriminating the graphic pattern by those feature values.
CONSTITUTION: Analog picture data inputted from input unit 1 is converted into binary data by binary-coding circuit 4 and feature-point extraction circuit 5 detects sequentially feature points, one by one. Then, region indication circuit 6 determines by region assignment signal 7a from region assignment control circuit 7 which of regions detected feature points belong to, and feature-point information is sent to decision circuits 8W10 corresponding to regions. Those decision circuits 8W10 decide upon the graphic pattern of each region and those results are synthesized by synthesizer circuit 11 to discriminate the graphic patterns of all regions of a picture surface.
