摘 要: 在对舌图像的去噪过程中,平滑噪声的同时容易丢失边缘和纹理等细节信息。为此,研究基于偏微分方程的舌图像去噪方法,分别采用中值滤波、高斯滤波、P-M方程、正则化P-M方程以及耦合冲击-复扩散滤波模型,对加噪舌图像进行滤波。比较结果表明,正则化P-M方程更适合舌图像的去噪处理,该方法处理速度快、去噪效果好,且能有效保护图像边缘。 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 tougue images. It has fast speed and good denoising result, and the best preserving for edges.
