Could you please explain what data is needed for training the SPM in the paper? The supplementary materials mention datasets including CI: Corrupted Images, II: Intact Images, CM: Corrupted Masks, ISM: Intact Segmentation Masks, CSM: Corrupted Segmentation Masks, IG: Intact Glyphs, and CC: Character Coordinates. However, the train_spm config only loads two types of images. Which two should be used? Should it be CI: Corrupted Images and II: Intact Images, or CI: Corrupted Images and ISM: Intact Segmentation Masks?

we offer diverse information for the subsequent in-depth research. In this study, we solely utilized Corrupted Images (as input) and Intact Segmentation Masks (as output) for the training of SPM.
