| 摘 要： | 为了滤除图像中高密度椒盐噪声同时又能较好地保护图像细节,提出一种自适应开关中值滤波算法。使用max-min算子作为噪声检测器,利用自适应邻域窗口对图像进行从左到右的逐行扫描,同时对位于窗口中心的像素点进行噪声判别,然后将检测出的噪声点采用中值滤波进行滤除,而信号点保持不变直接输出。实验仿真结果证明了该算法的有效性。

| Abstract: | In order to preserve more details in an image while removing high density salt and pepper noise,in this paper we propose an adaptive switch median filtering algorithm.We use max-min operator as the noise detector to progressively scan the image from left to right by means of adaptive neighbourhood window,and meanwhile discriminate the noises from the pixels in centre of the window,and then filter out the detected noise with median filtering but output the signal points directly without changes.Simulation re... |
