tl;dr

RealSR sharpens blurry, noisy real-world photos by learning how actual camera degradation happens, unlike tools trained only on artificially blurred images, it won CVPR NTIRE 2020's top prize.

prompt 1
Show me how to run RealSR's pre-trained model on a folder of my own low-quality photos.
prompt 2
Explain how RealSR estimates real blur kernels instead of using synthetic degradation like other super-resolution tools.
prompt 3
Walk me through preparing a dataset and training my own RealSR model from scratch.
