Abstract

An adaptive rank-order based switching median filter is proposed in this paper for the restoration of digital images corrupted with salt & pepper impulse noise. A more ideal and efficient impulse noise filter, the ARSMF detects all the corrupted pixels even when the image is highly corrupted and restores them with a more perfect signal detected from an appropriate region whose dimensions vary adaptively with noise levels. This noise replacing signal does the dual functions of noise suppression and detail preservation than many other variants of impulse noise filters. Experimental results, the subjective and objective analysis add to the efficiency and fidelity claim of the proposed ARSMF
椒盐脉冲降噪的自适应秩序切换中值滤波器
本文提出了一种基于自适应阶序的切换中值滤波器,用于椒盐脉冲噪声损坏的数字图像的恢复。作为一种更加理想和高效的脉冲噪声滤波器,ARSMF可以检测到所有损坏的像素,即使图像被高度损坏,并从适当的区域检测到更完美的信号,该区域的尺寸随噪声水平自适应变化。与许多其他类型的脉冲噪声滤波器相比,这种噪声替代信号具有抑制噪声和保留细节的双重功能。实验结果、主观和客观分析均证明了该算法的有效性和保真度
