We have sucessfully deployed model on iPhone Xs Max. The real-time demo is shown below:

The quantitative results are:

Besides, you are welcome to explore the phenomenon found in the paper with us. The phenomenon is about the relationship between PSNR and the NME of shallow features and deep features, which is shown below:
