CHARACTER RECOGNITION BY MATCHING SEQUENCES OF PSEUDOSTROKE POSITIONS AND DIRECTIONS
Hongxi Xue, V. Givindaraju · 2004
Chaincoded contours are informative in offline character recognition. As approximations to contours, sequences of pseudostrokes consisting of both positional and directional information make up feature vectors for character images. In order to carry out fast pattern matching, a scheme of generating fixedlength feature vectors that combine information about outer contour and inner contours into a uniform data structure is proposed and tested on CEDAR databases.
