METHOD AND SYSTEM FOR COMPRESSING HANDWRITTEN CHARACTER TEMPLATES

摘要

A method and system for compressing handwritten character templates. The system includes a codebook generator module (105) for generating a codebook (125). The codebook (125) includes vectors defining the centers of clusters (115) of uncompressed model character feature vectors (110) provided from model character templates. A template compression module (120) is connected to the codebook generator module (105) for comparing the uncompressed model character feature vectors (110) with the codebook (125) to provide compressed templates of model characters (135). Optionally, a template matching module (140) is connected to the template compression module (120) for providing candidate characters (150) by comparing the distances between uncompressed input character feature vectors (130) and the model character templates.
