摘要
介绍了一种基于四阶偏微分方程(PDE)噪声消除方法。采用分片平面图像逼近被处理图像。在噪声消除同时保持良好边缘,避免了使用二阶偏微分方程处理图像常常出现的块效应。实验结果表明该方法是行之有效的。
Demonstrate a method for noise removal based on fourth-order partial differential equations(PDE). Approximating image with a piecewise planar image can remove noises while preserving edges well and avoiding blocky effects which is easily seen in images processed by second order PDE. The application result indicates this method is efficient.
