Set5, Set11, and Set14 are classic small-scale benchmark datasets widely used for image super-resolution tasks. BSD100 and BSD500 feature complex natural scenes, commonly used for denoising and segmentation research. McM18 is a medical imaging dataset focused on medical image reconstruction. Urban100 emphasizes urban scenes, ideal for evaluating models on high-frequency details and structural textures. These datasets span diverse applications, serving as valuable benchmarks in computer vision research.
