Fixed-value impulse noise suppression for images using PDE based Adaptive Two-Stage Median Filter
P. Shanmugavadivu, P. S. Eliahim Jeevaraj · 2011
This paper presents a newly devised noise filter namely, Adaptive Two-Stage Median Filter (ATSM) to denoise the images corrupted by fixed-value impulse noise. The performance of the proposed filter is proved to be better in terms of Peak Signal-to-Noise Ratio and human visual perception. This filter is effectual in denoising the highly corrupted image with the noise probability of 90%.
