Place pretrained models here.

We provide two pretrained models:

1. RRDB_ESRGAN_x4.pth: the final ESRGAN model we used in our paper.
2. RRDB_PSNR_x4.pth: the PSNR-oriented model with high PSNR performance.

Note that the pretrained models are trained under the MATLAB bicubic kernel. If the downsampled kernel is different from that, the results may have artifacts.
