Before you get started

To run these scripts, you need the following installed:

1. Python 3
2. OpenCV 3 w/ Python extensions

• I highly recommend these OpenCV installation guides: https://www.pyimagesearch.com/opencv-tutorials-resources-guides/

3. The python libraries listed in requirements.txt

• Try running "pip3 install -r requirements.txt"

Run

./bin/download_img.sh 

Download images into the dir 'origin'

Step 1: Extract single letters from CAPTCHA images

Run:

python3 denoise2.py

denoies the captcha images. by this, the capacity will be better.

Run:

python3 split2.py

The results will be stored in the "extracted_letter_images" folder.

Step 2: Train the neural network to recognize single letters

Run:

python3 train_model2.py

This will write out "captcha_model2.hdf5" and "model_labels2.dat"

Step 3: Use the model to solve CAPTCHAs!

Run:

python3 slove2.py

有2套模型，一套基于大小split. 一套基于颜色抓取。
