An On-Line Chinese Character Recognition System

This paper describes an experimental system for the on-line recognition of handwritten Chinese characters. Constituent shapes of the characters are recognized as they are formed on an electronic tablet. The 72 constituent shapes can define a very large set of Chinese characters. The implementation described recognizes more than 2200 Chinese characters. More symbols can be added with relative ease. Experimental results are given for two writer populations.

Recognition of printed chinese characters by automatic pattern analysis

An approach to pattern recognition by computer, using analysis of pattern structure, isexplored. The approach is programmed and tested on a set of Chinese characters. The input to the program is a black-white matrix of points depicting a single character. The program produces a description of the character on two levels: (i) the internal structure of each connected part of the character, and (ii) the arrangement in two dimensions of the connected parts. The description is achieved by producing a structural representation of the character. The structure corresponding to level (i) is a graph, the edges of which correspond to parts of strokes. The structure corresponding to level (ii) is a tree, whose terminal elements correspond to connected parts of the character and whose nodes correspond to geometric relations. A method has been devised for producing a numeric code for each character. The codeis generated from the structural representation of a character, and is used for recognition.
