类似于Python验证码的图像失真 [英] Python CAPTCHA-like image disortion

问题描述

我想按照标准CAPTCHA对字体进行分类的方式对某些图像进行分类。我将如何在python中实现它？我应该使用哪些库/算法？有任何概念证明吗？

I would like to disort some images the same way standard CAPTCHA disorts fonts. How would I achieve it in python? What libraries/algorithms I should use? Any proof-of-concept?

免责声明：在询问这个问题之前，我已经搜索了一段时间，但找不到满意的答案。我是该领域的新手，所以我无法提供任何证明我的研究努力的代码...

DISCLAIMER: I was googling for some time before I asked this question but I couldn't find any satisfying answer. I'm new to the field so I can't provide any code proving my 'research effort'...

推荐答案

I认为您正在寻找PyCaptcha http://svn.navi.cx/misc/trunk/pycaptcha/

I think you are looking for PyCaptcha http://svn.navi.cx/misc/trunk/pycaptcha/

要扭曲的实际代码在这里： http://svn.navi.cx/misc/trunk/pycaptcha/Captcha/Visual/Distortions.py

The actual code to distort is here: http://svn.navi.cx/misc/trunk/pycaptcha/Captcha/Visual/Distortions.py

该工作是由PIL的转换函数，例如：

The work is done by PIL's transform function, like this:

image.transform(image.size, Image.MESH, mesh, self.filtering)

其余的代码本质上是用来生成所使用的网格的。

The rest of the code is there essentially to generate the mesh that is used.
