OCR (Optical Character Recognition,光学字符识别)是指电子设备(例如扫描仪或数码相机)检查纸上打印的字符,通过检测暗、亮的模式确定其形状,然后用字符识别方法将形状翻译成计算机文字的过程;即,针对印刷体字符,采用光学的方式将纸质文档中的文字转换成为黑白点阵的图像文件,并通过识别软件将图像中的文字转换成文本格式,供文字处理软件进一步编辑加工的技术。如何除错或利用辅助信息提高识别正确率,是OCR最重要的课题,ICR(Intelligent Character Reco

本程序主要参照论文,《基于OpenCV的脱机手写字符识别技术》实现了,对于手写阿拉伯数字的识别工作。识别工作分为三大步骤:预处理,特征提取,分类识别。预处理过程主要找到图像的ROI部分子图像并进行大小的归一化处理,特征提取将图像转化为特征向量,分类识别采用k-近邻分类方法进行分类处理,最后根据分类结果完成识别工作。
程序采用Microsoft Visual Studio 2010与OpenCV2.4.4在Windows 7-64位旗舰版系统下开发完成。并在Windows xp-32位系统下测试
