DeanCaptcha——机器学习识别验证码

这是我们《数据结构与算法实习》课程的作业。我们要写一个识别北京大学教务网的验证码的程序。

我们的思路

}

预处理:去噪声 二值化 分割 naive算法

学习的三种方法:

  • k邻近 没用!全失败了!
  • 机器学习!成了!
  • 深度学习:没写完那!

封装成成品程序。

体会:

  • 不要瞎用数据库。

need json like:

{ '10101...1010':'A', '1010101001..1':'1', ..............}

Attention! : numbers like '1' must be given by char alphabet like 'A' must be given by Capital char

curl "http://dean.pku.edu.cn/student/yanzheng.php?act=init&rand=[0-5]" -o "#1.gif"
