Training

if you use one gpu or multiple gpu using data parallel, run

sh sh_train_mssnet.sh

if you use multiple gpu using distributed data parallel, run

sh sh_train_mssnet_ddp.sh

Arguments

• train_datalist : Text file with the path of image for training

• val_datalist : Text file with the path of image for validation

• checkdir : Path to save checkpoints

• loadchdir : Path of checkpoint to load

• data_root_dir : Root path of data in train_datalist

• val_root_dir : Root path of data in val_datalist

• isloadch : Whether to load checkpoint

• isval : Whether to use validation

• mgpu : Whether to use multiple gpu

• wf, scale, vscale : Hyper-Parameters for channel size

  Model	wf	scale	vscale
  MSSNet_small	20	40	40
  MSSNet	54	42	42
  MSSNet_large	80	50	50

Testing

Run

sh sh_test_mssnet.sh

Arguments

• test_datalist : Text file with the path of image for testing
• data_root_dir : Root path of data in test_datalist
• load_dir : Path of checkpoint to load
• outdir : Path to save test results
• is_save : Whether to save test results
• is_eval : Whether to evaluate the model on the GoPro test dataset using psnr of skimage.metrics

Evaluation

Run evaluate_gopro.m file to evaluate model on the gopro dataset.
This code is based on the MPRNet.

Acknowledgment

The code is based on the MPRNet, MIMO-UNet and ddp_example.
