Solver for the geetest sliding captcha, implemented with Python and the OpenCV package.

NOTE: THIS SOLVER HAS BEEN TESTED ON PRODUCTION CAPTCHAS

To pass this captcha, the piece need to be moved to his gap.

Here's an example of the captcha:

For this solver, we just need the 2 images that form this captcha (piece and background):

You can find these images in the html of the web page. For example:

<canvas class="geetest_canvas_bg geetest_absolute" height="160" width="260"></canvas>
<canvas class="geetest_canvas_slice geetest_absolute" width="260" height="160"></canvas>

The solution of this captcha is the distance between the piece at the beginning and the piece's gap. So if the solver matches the gap, it has the solution.
