Finger detection and removal in document image

Question

I'd like to detect fingers in the image and remove them for book scanning. I have searched for finger detection and object removal projects but none of them could easily be applied or the results were not good. So, I might have to start writing my own code..

Could you recommend useful algorithms for the below items? I think,

1) Drawing a contour (including shadows)

2) Select the finger region

3) Context-aware-fill where the finger was

I tried, https://github.com/VPanjeta/Deep-Object-Removal

Thanks in advance
