# CNN_Keras

__:star: Switch to branch [pytorch](https://github.com/skyduy/CNN_keras/tree/pytorch) to see big changes! It uses PyTorch as framework and uses a more robust method!:star:__

## Introduction

[Convolutional Neural Network](https://en.wikipedia.org/wiki/Convolutional_neural_network) using [Keras](https://github.com/fchollet/keras/tree/master/keras) for [CAPTCHA](https://en.wikipedia.org/wiki/CAPTCHA) recognition.

Recognition for this type of CAPTCHA:

![3](https://github.com/skyduy/CNN_keras/blob/master/samples/YRY8S.jpg)

Actually these CAPTCHAs are generated from repo [CAPTCHA_generator](https://github.com/skyduy/CAPTCHA_generator).

## Achievement

Using about 5000 samples, Obtain 95% single letter accuracy.
