如何识别一张图片上的数字?
如何识别一张图片上的数字?那位高手有算法,分享一下! 曾经设计过这样的一个算法。另外，如果你贴上图片的话可能问题会比较容易解决 本帖最后由 tryhi 于 2011-6-30 16:00 编辑
这一个5*8的像素组成的数字根据其中七点（不知道能不能用6点，反正我最少想出七点）判断出数字。
If $numx1 = 1 And $numx2 = 0 And $numx3 = 0 And $numx4 = 0 And $numx5 = 0 And $numx6 = 0 And $numx7 = 0 Then Return 0
If $numx1 = 0 And $numx2 = 0 And $numx3 = 0 And $numx4 = 1 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 1
If $numx1 = 0 And $numx2 = 0 And $numx3 = 0 And $numx4 = 1 And $numx5 = 0 And $numx6 = 0 And $numx7 = 1 Then Return 2
If $numx1 = 0 And $numx2 = 0 And $numx3 = 0 And $numx4 = 0 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 3
If $numx1 = 0 And $numx2 = 1 And $numx3 = 0 And $numx4 = 0 And $numx5 = 0 And $numx6 = 0 And $numx7 = 1 Then Return 4
If $numx1 = 1 And $numx2 = 1 And $numx3 = 1 And $numx4 = 0 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 5
If $numx1 = 1 And $numx2 = 1 And $numx3 = 0 And $numx4 = 0 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 6
If $numx1 = 0 And $numx2 = 0 And $numx3 = 1 And $numx4 = 1 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 7
If $numx1 = 0 And $numx2 = 1 And $numx3 = 0 And $numx4 = 0 And $numx5 = 0 And $numx6 = 1 And $numx7 = 0 Then Return 8
If $numx1 = 1 And $numx2 = 0 And $numx3 = 0 And $numx4 = 1 And $numx5 = 1 And $numx6 = 0 And $numx7 = 0 Then Return 9 验证码？？？ 不是,看来这个问题比较复杂,打算换一种思路来解顽皮遇到的问题了 这一个5*8的像素组成的数字根据其中七点（不知道能不能用6点，反正我最少想出七点）判断出数字。

请问,你这算法是基于哪种字体的?能有通用的算法吗? 楼主想做验证码么？？？ 请问,你这算法是基于哪种字体的?能有通用的算法吗?

字体我忘了，好像跟右下角的时间同种字体，没有通用性，必须5x8，而且是确定字体，可惜我确定点的分析过程被我删了，不然对你应该有用。我这个月不用电脑，所以没办法详细说了
