 The model is trained on a TITAN Xp GPU with patch size of 96*96 and total 70000 iterations.
 
 Several groups of simulated images are uploaded at [here](https://github.com/z-bingo/FastDVDNet/blob/master/results). The FastDVDNet could work well based on the Vimeo-90K dataset totally, one of results is shown as
