Superresolution using an efficient sub-pixel convolutional neural network

This example illustrates how to use the efficient sub-pixel convolution layer described in "Real-Time Single Image and Video Super-Resolution Using an Efficient Sub-Pixel Convolutional Neural Network" - Shi et al. for increasing spatial resolution within your network for tasks such as superresolution.

usage: main.py [-h] --upscale_factor UPSCALE_FACTOR [--batchSize BATCHSIZE]
               [--testBatchSize TESTBATCHSIZE] [--nEpochs NEPOCHS] [--lr LR]
               [--cuda] [--threads THREADS] [--seed SEED]

  --upscale_factor      super resolution upscale factor
  --batchSize           training batch size
  --testBatchSize       testing batch size
  --nEpochs             number of epochs to train for
  --lr                  Learning Rate. Default=0.01
  --cuda                use cuda
  --mps                 enable GPU on macOS
  --threads             number of threads for data loader to use Default=4

This example trains a super-resolution network on the BSD300 dataset, using crops from the 200 training images, and evaluating on crops of the 100 test images. A snapshot of the model after every epoch with filename modelepoch<epoch_number>.pth
