In this paper, a technique of maintaining the details in filtering is studied and a detail-preserving adaptive filter algorithm based on difference is proposed.
本文研究如何在滤波的同时实现细节的保留，提出一种基于差分的细节保留自适应滤波算法。
The filtering window size is reduced as small as possible. The better results of detail preserving are obtained.
新算法尽可能地减小了滤波窗口，使得图像细节得到更好的保持。
