Pytorch implementation

We provide simple Dataset modules for adopting our pipeline. This is slightly different from the tensorflow implementation.

Please refer to Uformer-RSBlur.

# ./Uformer-RSBlur/dataset/dataset_RealisticDeblur.py

class RealisticGoProABMEDataset(Dataset):
    def __init__(self, image_dir, patch_size=256, image_aug=True, realistic_pipeline=True):
        ...

    def __len__(self):
        return len(self.image_list)

    def __getitem__(self, idx):
        ...

class RealisticGoProUDataset(Dataset):
    def __init__(self, image_dir, patch_size=256, image_aug=True, realistic_pipeline=True):
        ...

    def __len__(self):
        return len(self.image_list)

    def __getitem__(self, idx):
        ...
