【摘要】This paper proposes a special algorithm for filtering out both Ganssian and impulse noises in color images. Firsdy, the impulse noises are filtered out by the median filtering method through determining the number of impulse dots. Following that the Gaussian noises are filtered out by symmetrical-neighbor mean filtering. As a result, the experiment shows that the algorithm can effectively filter out Gaussian and impulse noises, as well as preserve more detailed information of the original image.%提出了一种彩色图像混合滤波算法,时混有高斯和脉冲噪声的图像进行去噪处理.算法首先滤除受昧冲噪声污染的像素点,采用基于个数判断脉冲噪声的中值滤波算法;其次滤除受高斯噪声污染的像素点,采用对称近邻均值滤波算法.实验结果表明,与传统的中值滤波和均值滤波算法相比,该算法能够有效地去除高斯和脉冲噪声,同时能够保留更多的图像细节信息. 【总页数】2页(5217-5218)
