This article design implementation has a based on Matlab software of handwriting body digital recognition system, used module of design method, write has camera entered, and directly read pictures, and write Board entered three a module, using camera, tools, will to text form exists of handwriting body digital entered into puter, pleted on handwriting body digital pictures of collection, and design has a handwriting digital recognition method, on handwriting body digital image for pretreatment, and structure features extraction, and classification recognition, eventually to text form output digital, to implementation handwriting body digital of recognition.Key words: Pretreatment, structure feature extraction, classification and recognition, handwritten digit recognition.目錄 II目
