基于偏微分方程的舌图像去噪研究
Research of Tongue Image Denoising Based on Partial Differential Equation
摘要
Abstract
When denoising the tongue image, the details such as the edges and the veins are easy to be lost. Aiming at this problem, this paper proposes a new method to denoise the tongue image based on Partial Differential Equation(PDE). It applies median filtering, Gaussian filtering, P-M equation, regularization P-M equation and Coupling shock filtering combined complex diffusion filtering model to denoise the noising tongue images. Comparison result shows that the regularized P-M equation is the best method to denoise the tongue images. It has fast speed and good denoising result, and the best preserving for edges.关键词
