         * 开发思路：图片灰度处理，二进制，然后和图片中的字二进制库精确对比
         * 
         * 获取字库：通过下面代码中generateLicense（Bitmap singlepic）方法获得，具体操作：
         *      从图片中截图出（抠出）一个字符，然后处理得到二维的二进制矩阵，比如下面的字符1对应的二维矩阵
         *      00000
         *      00100
         *      11100
         *      00100
         *      00100
         *      00100
         *      00100
         *      00100
         *      00100
         *      11111
         *      00000
         *      00000
         *      
         * 注意：【相同字符，比如1，不同字体，字号，不同缩放大小的图片，获得到的二位矩阵中0、1排列和数量都是不同的！
