本文提出了两种同时受脉冲噪声和高斯白噪声污染图像的基于区域生长的细节保护滤波器。本方法由于利用了图像的空间结构信息及像素的幅序信息，因而能较好地解决图像细节保护与噪声滤除的矛盾。在区域生长算法中采用了自适应阈值，能自适应地确定参与滤波运算的像素。文中还给出了模拟实验的结果。
In this paper, we propose two region-based details-preserving filters that are contaminated by both impulse noise and Gaussian white noise. Due to the use of the spatial structure of the image information and the pixel sequence information, the method can better solve the conflict between image detail protection and noise filtering. Adaptive thresholds are used in the region growing algorithm to adaptively determine the pixels involved in the filtering operation. The article also gives the result of simulation experiment.
