基于最大后验概率的la范数去噪方法
Denoising Method Based on the MAP with la Norm
摘要
Abstract
In the paper, from the observation model and a priori model, the problem of image denoising is discussed, and how to find a balance between edge protection and image denoising is analyzed in depth.In addition, aiming at the advantages and disadvantages of TV prior model on the edge protection and texture protect, the new denoising method named la norm based on Maximum A Posteriori Probability(MAP) is put forward.This method provides better protection of the edge of the image.Furthermore, the staircase effect in smooth regions is reduced.Numerical simulations are further provided to verify the feasibility and effectiveness of the theoretical results.关键词
