一种新的加权组合图像去噪模型
A New Weighted Combination Model for Image Denoising
摘要
Abstract
Aiming at the staircase effect and isolated point in the classical models of PM model and YK model,the paper proposes a combinatorial operator model.Regularization is performed on the image to be processed.The gradient in the above-mentioned classical models is combined with Laplace operator according to certain weighting function.Then,in view of the phenomenon of excessive smoothing in nonlinear diffusion,this paper uses edge harmonic operator for modification.Experimental results show that this model not only effectively controls the staircase effect and isolated point,but retains the detailed texture features of the image quite well,and it has an obvious denoising effect.关键词
