• [1] Yet Another Text Captcha Solver: A Generative Adversarial Network Based Approach

• [2] pix2pix

Go for code -> Out of the box Step one Real Captcha image like this Step two Using PIL Make fake image like this

Step three Combine Paired data

python datasets/combine_A_and_B.py --fold_A /pix2pix_working/sf --fold_B /pix2pix_working/sf_fake --fold_AB /pix2pix_working/sf_A_B

Step last Train Model

cost 10min ,about 50 epoch when convergence

python train.py --dataroot  /pix2pix_working/sf_A_B --name sf_pix2pix --model pix2pix --direction AtoB --batch_size 32 --preprocess none --no_flip 

Inference

python test.py --dataroot  /pix2pix_working/sf/test --name sf_pix2pix --model test --direction AtoB --dataset_mode single --norm batch --preprocess none
