Train a CNN model to identify captcha code with TensorFlow and Keras
In the last post (Automatically fill in captcha code in course selection system), we exploited the "Play Audio" button function to obtain the captcha code in the course selection system from my college. Today, we will be going through another approch to identify the captcha code by training a CNN model with TensorFlow and Keras.
A captcha code from the course selection system.
