Kaggle Carvana Image Masking Challenge solution with Keras

This solution was based on Heng CherKeng's code for PyTorch. I kindly thank him for sharing his work. 128x128, 256x256, 512x512 and 1024x1024 U-nets are implemented. Public LB scores for each U-net are:

U-net LB score
128x128 0.990
256x256 0.992
512x512 0.995
1024x1024 0.996
