Block matching with different block sizes and (non-) uniform distribution of block estimates.
(A) Noisy silicon lattice with dislocation (peak 6, PSNR: 2.70 dB), (B) noisy perfect silicon lattice (peak: 6, PSNR: 3.62 dB), (C) and (D) corresponding estimates from adaptive periodic block-matching BM3D using N
1=8, (E) and (F) using N
1=16, and (G) and (H) using N
1=16 and uniform distribution of block estimates.
