StainDoc

High-Fidelity Document Stain Removal via A Large-Scale Real-World Dataset and A Memory-Augmented Transformer

StainDoc is constructed, the first large-scale, high-resolution dataset specifically designed for document stain removal, and StainRestorer, a Transformer-based document stain removal approach, is proposed, demonstrating superior performance over state-of-the-art methods on the Stain-Doc dataset and its variants StainDoc.Mark and Stain-Doc.Seal.
