# CaptchaIdentifier

Image Captcha Solving Using TensorFlow and CNN Model，with self-labeling image Dataset，free to download my Dataset for  self-learning. accuracy 95%+.

 

Note:this implementation, in some way, is kind of  rough, but effective. hope to motivate your inspiration to do better work. 

# Description

- original Data

  * raw_img shape:100*120

- preprocessed Data

  * preprocessed_img shape:100\*120*1

- accuracy

  after training, the accuracy is 95%+, managing to identify complex captchas, as below:

# DataSet

  Happy to contribute the dataSet, images are from a real website, labling by tired  eyes and numb hands, so if you think it can do some kind of help,  star it. Thank you! download the data by [Baidu Pan](https://pan.baidu.com/s/1iK3D0sDkbM6_u-LKpgs2Yg),

sharing code is: `oacx`，enjoy!
