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.
