一种基于偏微分方程的图像平滑技术

Image Smoothing Based on Partial Differential Equation

图像平滑是大多数图像分析和计算机视觉问题中必需的环节。文中探讨了噪声图像的噪声抑制方法,利用了基于偏微分方程的平滑技术。该方法的优点在于可以在消除噪声的同时有效地保持空间分辨率。最后采用数据验证了方法的有效性。

Image smoothing is a necessary part in the most problems on image analysis and computer vision. In this paper, a new adaptive approach based on the partial differential equation is put forward for removing the noise in the image. At the end of this paper, the experimental results by processing true data are used to confirm that the method is more effective in image smoothing.
