I browse the paper and the code but cant find any GAN mechanism in it。the paper say
"Our captcha generator model includes a image generator and a generator network. The image generator produces a captcha image at the word level, and the generator network modifies the produced captcha image at the pixel level to add security features."
But there is only a keras image generator in your code without any generator network. Cant find any trace of GAN
