分享，某网站验证码识别程序，识别率百分之百

首先，源码可以在这里下载，http://download.csdn.net/detail/koflfy/3932151早几天在论坛开了一贴，现在问题终于解决了，该程序对某个网站的验证码做识别，识别率百分之百，可以拿这个程序举一反三，现在还有很多网站都是用这种验证码的，包括我刚才上传资源的页面的CSDN的验证码都可以简单修改识别之，呵呵。。
之前处理完验证码图片后，分割图片进行x,y取点阵，后来发现有几个字符点阵有重复，所以不能百分百识别，后来在一位朋友的提醒下对验证码再做y,x取点阵，终于能百分百识别了，在研究的过程中，也学会很多东西，现放出源码，同时感谢 Sandy945 大牛。
