A pattern recognition system based on computer vision — The method of Chinese chess recognition

A Chinese chessman pattern recognition system is presented. First, system structure is introduced, and chessman image pretreatment is discussed. Then primarily discusses the chessman recognition algorithms. Because of direction haphazardry, chessman recognition is quite different from character recognition. This paper presents two kinds of chessman recognition algorithms — RC and concentric circle algorithm for feature extraction. Then choose a relatively suitable recognition algorithm by comparing their time complexity and accuracy.
