1、解析圖片驗(yàn)證碼--可以破解OK卡網(wǎng)站的驗(yàn)證碼文章分類(lèi):Java編程1，生成圖片請(qǐng)參照http://tristan-s.iteye.com/admin/blogs/10263072，目前只能解析沒(méi)有干擾素的數(shù)字圖片。例如：去除干擾素，可以用以下算法a>線(xiàn)條的：檢查該線(xiàn)條是否是貫通的直線(xiàn)條，如是則去掉b>點(diǎn)：檢查該點(diǎn)是否是孤立的，如是則去掉3，需要將圖片中的數(shù)字用0，1的形式來(lái)表達(dá)。解析每個(gè)數(shù)字，見(jiàn)附件4，代碼Java代碼?1.import?java.awt.image.BufferedImage;??2.import?java
