Adding CTC Loss and CTC decode to a Keras model

I am trying to solve a use case of handwritten text recognition. I have used CNN and LSTM to create a network. The output of this needs to be fed to a CTC layer. I could find some codes to do this in native tensorflow. Is there an easier option for…

How do I isolate handwritten text from an image using OpenCV and Python?

How do I isolate or crop only the handwritten text using OpenCV and Phyton for the image: I have tried to use: cv2.findContours but because of the noise (background and dirty in paper) I can't get only the paper. How do I do this?
