From: Poisson noise removal from high-resolution STEM images based on periodic block matching
Comparison between local and adaptive periodic block matching. Denoised versions of the Poisson noise affected images from Figure 3 after application of local block-matching BM3D (A), (C), (E), and (G) and non-local adaptive periodic block-matching BM3D (B), (D), (F), and (H). The block size is N 1=16 for both methods.
