CAPTCHA-Breaker

This repository contains the pipeline for breaking a text-based CAPTCHA using python and deep learning. The pipeline has the following 3 modules:

CAPTCHA-Generator is used to generate a limited dataset of text-based CAPTCHAs and there are different variations to choose from.
Pix2Pix is a GAN (Generative Adversarial Network) which is used to generate more of the selected variation of text-based CAPTCHAs.
CAPTCHA-Classifier is a CNN (Convolutional Neural Network) which is used to recognize the characters contained in the text-based CAPTCHA.

Prerequisites

Tensorflow 1.4.1
Python 3.x
OpenCV

How to run

Download the datasets and extract them inside the CAPTCHA-Generator\Images directory to be able to generate different variety of text-based CAPTCHAs having different background and textured alphabets.
Run the CAPTCHA-Breaker.bat file and you are good to go.
