Deep Unfolded BM3D: Unrolling Non-local Collaborative Filtering into a Trainable Neural Network

Kerem Basim, Mehmet Ozan Unal, Metin Ertas +1

Block-Matching and 3D Filtering (BM3D) exploits non-local self-similarity priors for denoising but relies on fixed parameters. Deep models such as U-Net are more flexible but often…
