Character Recognition by Matching Sequences of Pseudo-stroke Positions and Directions

OF PSEUDO-STROKE POSITIONS AND DIRECTIONS HANHONG XUE AND VENU GOVINDARAJU CEDAR, State University of New York at Bu alo, Bu alo, NY 14260, USA E-mail: fhxue, govindg@cedar.bu alo.edu Chain-coded contours are informative in o -line character recognition. As approximations to contours, sequences of pseudo-strokes 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 xed-length feature vectors that combine information about outer contour and inner contours into a uniform data structure is proposed and tested on CEDAR databases.
