Algorithm implementation of the "The Robustness of “Connecting Characters Together” CAPTCHAs". The test data set is the TAOBAO CAPTCHA that composed of blue character and white background.

1.This repository created in C# VS2013-x64, It contains the following function:

• merged characters segmentation algorithm according "The Robustness of “Connecting Characters Together” CAPTCHAs".
• Sauvola binarization
• OTSU binarization
• Iteration binarization
• Zhang-Suen skeletonization

2.The test data set is the TAOBAO CAPTCHA that composed of blue character and white background.
