PSNR calculation

[chensteven]

Hi,

How come you are calculating PSNR between the bicubic image and predicted image? Shouldn't it be the PSNR between ground truth and predicted?

Exactly, I agree with this!

I modified the program code and calculating PSNR between ground truth and predicted image. Then I used the best results of 400 training epoch. The reconstruction results seems OK, but the PSNR is very low(about 5dB). What's the problem?

I encountered the same problem. I trained on my dataset and directly trained RGB images. The effect was very poor, worse than Bicubic. Have you solved this problem?

大佬，你是怎么修改的？将GT图像转换为YCBCR空间再提取Y通道吗？
