Research and Optimization on BM3D Denoising Algorithm
Zhenwei Guo, Xiao Bo Zhou · Applied Mechanics and Materials · 2014
By grouping up the similar blocks in the picture and Collaborative Filtering, BM3D gets a good denoising effect. But denoising performance declined when the noise enhanced. A reason of poor denoising effect in strong noise was put forward in this paper. Then the denoising ability of BM3D was enhanced by optimizing the parameters.BM3D is proved superior to the traditional filtering denoising algorithm and the optimized BM3D gets a better effect than the original one in strong noise in simulation.
