CAPTCHA breaker

This is just an experiment made for a school project. It works only for a specific kind of CAPTCHA, which you can find on this website: http://sistemas3.sef.sc.gov.br/sintegra/consulta_empresa_pesquisa.aspx

It's missing some files:

• the model: models/sintegra_sc_model.ckpt
• the images: images/

Model

To get a model that recognizes CAPTCHAs, you will need to train a Neural Network using the captcha_train.py script.

Images

To train the model you will need to download a lot of images (about 500k) and rename all of those images with the correct characters from inside the image. Then you can split about 85% of those images in the images/train/ folder and the rest in the images/test/ folder.

The project

If you want to know more about the project and you understand portuguese you can read about my work: TCC.
