识别网站验证码。自己以前写的，只能针对数字字体固定的那些验证码。采用idhttp下载验证码图片，V0~~V9是数字0~~9的特征码，通过比较数字的特征码相似百分比来判断这个是什么数字。识别率较高。 本程序不是通过复杂的数学算法来实现。所以难度不高，只是游戏之作，不喜勿喷！-Identification codes. Their written before, only those fixed font for digital verification code. Using idhttp download Captcha Image, V0 ~ ~ V9 is a number from 0 to 9 signatures, digital signatures by comparing similar percentage to determine what is this number. High recognition rate. This program is not through complex mathematical algorithms to achieve. So the difficulty is not high, but as a game, do not like do not spray!
