The difference between PSNR, PSNR_f, PSNR_c #7

Thanks for your great work. But I have a question about three PSNR values during training and testing.

During training, there were PSNR, PSNR_fine. What are difference between these two? It seems the two have different values.

Also, there were only PSNR_f, PSNR_c after testing. What are difference between these two? It also seems the two have different values. In this case, how can I get PSNR value just like the metrics you posted?

PSNR_c and PSNR_f correspond to the PSNR obtained from the coarse or the fine network (used with hierarchical sampling). PSNR corresponds to the final value (PSNR_f in the case of hierarchical sampling, or PSNR_c when we only do a single sampling using a single network).
