基于偏微分方程的含噪图像复原新模型
A New Image Restoration Model Based on Partial Differential Equation
摘要
Abstract
Aiming at the shortcomings of the existing total variation and fourth order partial differential equation (PDE) image restoration model, a new image restoration model is put forward.The ideal of the new model is to combine the two models, at the same time, by modifying a diffusion coefficient of the equation, to achieve the enhancement purpose to the effect of image denoising.The new model not only makes the image edge details be protected and the "ladder effect" be restrained, but also has high signal-to-noise ratio.Theoretical analysis and MATLAB simulation results show that the recovery image quality is higher after the new model dispose, and also have a good visual effect, fully embodying the effectiveness of the new model on image restoration.关键词
