Hello, have you tried losses such as DISTS or LPIPS?

Hello, congratulations for your work, I have the impression that the L1 loss gives very good results on the metric of the PSNR without the good visual quality. Have you studied the possibility of using a loss funciton such as DISTS or LPIPS mixed with an L1 loss function ?

Have a nice day.

There have been some works that try the mixed loss with DISTS or LPIPS. The purpose is to improve the visual quality. You can find these works and have a try.
