SORD reconstructs localized structured corruption using a support mask and a diffusion prior for the desired clean-signal class. It initializes candidates by inpainting, then iteratively reuses corrupted measurements while refining residuals. On MNIST digits overlaid on CelebA, its corrupted-region pixel-reconstruction score is 27.16 ± 2.04 dB, versus 22.51 ± 3.89 for masked SGM; results depend on an accurate mask.
