The Lattice Boltzmann Method Based Image Denoising
Yuehong Qian · Dianzi xuebao · 2009
The diffusion model proposed by Perona and Malik is unstable.This will lead to the in image denoising.The lattice Boltzmann anisotropic diffusion model(LBADM) is proposed by introducing a medium between the nodes of the lattice based on the lattice Boltzmann isotropic diffusion model(LBIDM).The force represented by the forward diffusion process dominates in the LBADM.This means the Lattice Boltzmann model LBADM is stable.The experiment and discussion showed that our algorithm can overcome the staircasing effect of the P-M model well.Compared to the Perona and Malik's isotropic diffusion model,the lattice Boltzmann anisotropic diffusion model had higher peak signal-to-noise ratio.
