| 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。 |

| 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 tougue images.It has fast speed and good denoising result,and the best preserving for edges. |
| Keywords: | tongue diagnosis Partial Differential Equation(PDE) image denoising P-M equation shock filtering complex diffusion |
