Utilis module: a module for auxilary functions

multiprocessing for pre-processing NIFTI volumes
metrics calculation and logging
adding noise to simulate noisy images for denoising

Inference

using whole-brain inference

Generate LR whole brain volume
Infer them to get whole brain SR volume
Suggested to be used on device=cpu when your GPU mem is low

or using individual-patch inference

Take a whole brain volume, downsample to LR
Patch them into overlapped volumes
Infer individual LR patches to get SR patches
Assemble them to get a SR whole brain volume
