P-M与TV模型在加性高斯白噪声去噪中的比较研究
A Comparative Stu dy betwe n P-M and TV Models In Additive White Gaussian Noise Denoising
摘要
Abstract
Noise is inevitable phenomenon in the process of image acquisition , transmission and storage .As the first step and the basic problem of image processing , denoising is the foundation of subsequent high level image processing .This paper, taking the additive white Gaussian noise as an example , summarizes the principle of the P-M diffusion equation and TV model , and compared the denoising effect from two aspects of visual and quantitative indicators .Finally, under the condition of pretreatment of thermal dif-fusion equation model , it compared the effect of denoising of the two models .关键词
