形状上下文算法。做好预处理后，使用此算法匹配验证码，识别率非常高，且无视扭曲，变形。-The shape context algorithm. Do a good job pre-treated using this algorithm matches the verification code, recognition rate is very high, and ignore the twisted, distorted.

基于MATLAB的HOPFIELD字母识别算法！！ 可以识别形状不全的字母-MATLAB-based recognition algorithm HOPFIELD letters! ! Failure to identify the shape of the letters

形状上下文算法。做好预处理后，使用此算法匹配验证码，识识别率非常高，且无视扭曲，变形。， -Shape context algorithm. Do pretreatment, the use of this algorithm to match the verification code, the knowledge is very high recognition rate, and ignoring the twisted, distorted. ,
