Abstract:

As the current pattern recognition methods are mainly based on the distinction mechanism instead of the cognition mechanism,this paper,considering the achievements of pattern recognition in the cognitive psychology,proposes a new pattern recognition method based on the prototype matching.Moreover,the recognition mechanism,mathematical model and recognition algorithm of the proposed method are discussed in detail.In the proposed method,the pattern recognition is defined as a problem consisting of the components,such as the prototype,the structure and the configuration rule,and the recognition task is accomplished by using the prototype and knowledge repositories constructed with the three above-mentioned components.Recognition results of digital character images indicate that the proposed method is valid.

Key words: pattern recognition, cognitive system, cognitive psychology, prototype, coverage
