基于差分的细节保留自适应滤波算法

A Difference-Based Detail-Preserving Adaptive Filter Algorithm

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。该算法利用噪声点的灰度不一致性 ,通过差分来区分象素点 ,针对不同类别的象素点进行自适应处理。实验结果表明 ,该算法在去除脉冲和高斯噪声的同时 ,能很好地保留图像的细节。

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. The algorithm distinguishes the pixels by differences based on the grey value discontinuity of the noised pixels. Experimental results show that by using this algorithm,the details can be preserved well,and impulses and the Gaussian noise can be removed effectively at the same time.
