基于变分偏微分方程的双参数图像去噪模型
Image denoising model based on variational partial differential equation with double parameters
摘要
Abstract
This paper presents an image denoising model based on Variational Partial differential equation with double parameters. Firstly,using the minimax principle of variational method,this paper proves that the double parameters model has an unique minimal value,then it gives the corresponding Euler-Lagrange equation. Secondly,According to the given discrete format of partial differential equation,it denoises some noise images. Comparing the results with Rudin,Osher and Fatemi model(ROF model) ,the results show that double parameters model in visual and kurtosis signal-to-noise ratio has better denoising effect.关键词
