1. move all images (train and test) to folder datasets and creat .h5 file

python create_YTC_xin.py

If you want to use your datasets, try to modify the code as follows.

#52 x = create_YTC(pathfolder, 18) the size of low-resolution images <br><br> #61 x = create_YTC(pathfolder, 144) the size of high-resolution images <br><br>

2.train URDGN

th train_ytc_xin_128_D.lua

just change the code of train_ytc_xin_128_D.lua <br><br> #39 --scale (default 144) the size of high-resolution images <br><br> #48 ntrain = 1600 the num of train images <br><br> #49 nval = 40 the num of test images <br><br> #112 model_D:add(nn.Reshape(9 *9 *96)) --9 = 144 / (2 ^ 4) <br><br> #113 model_D:add(nn.Linear(9 *9 *96, 1024)) <br><br> #198 local noise_inputs = torch.Tensor(N, 3, 18, 18) <br><br> #204 noise_inputs[{{i}}] = image.scale(torch.squeeze(noise_input_high[{{idx}}]),18,18) <br><br> #224 local to_plot = getSamples(valData_HR, 40) the num of test images <br><br> #232 local formatted = image.toDisplayTensor({input=to_plot, nrow=10}) <br><br> #239 IDX = torch.randperm(1600) the num of train images <br><br>

just change the code of adverserial_xin_v1_D.lua <br><br> #135 local LR_inputs = torch.Tensor(opt.batchSize, 3, 18, 18) the size of low-resolution images <br><br> #243 local sample = torch.Tensor(dataBatchSize, 3, 18, 18) the size of low-resolution images <br><br> #348 local inputs_lr = torch.Tensor(opt.batchSize, 3, 18, 18) the size of low-resolution images <br><br>

3.This code can split the result and save them as images in folder sr

run getimg.m
