P. Shanmugavadivu, P. S. Eliahim Jeevaraj · 2012
This paper presents a newly devised noise filter namely, “Laplace Equation based Adaptive Median Filter for highly corrupted images” (LEAM) 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 proved to be effective in denoising even the highly corrupted images with the noise probability of 90%.
