Abstract

Abstract: Chalk handwriting is widely used in the production or usual life.After analyzing chalk handwriting features，the automatic recognition method of chalk handwritten numerals is proposed.Two main issues of segmentation and recognition are solved through the universal chalk handwritten segmentation algorithm and the hierarchical classification automatic recognition technique based on SVM.The experiment is executed during the application of the automatic recognition system of steel slab numbers，which proves that the method can achieve high recognition ratio.This method can reach the requirements of application，and has high value of application and significance of promotion.

Key words: chalk handwriting extraction, handwritten digit, feature selection, hierarchical classification, automatic recognition

摘要： 手写粉笔字在生产生活中应用广泛，针对手写粉笔字易与背景混淆的特点，提出了手写粉笔数字自动识别方法，分别通过粉笔字普适性分割算法和基于SVM的手写数字分层分类自动识别技术解决了分割和识别两个关键问题，并结合钢材板坯号自动识别系统的应用进行方法的实验，达到了较高的识别率，具有重大的应用价值和推广意义。
