A New Decision based Unsymmetrical Trimmed Midpoint algorithm, which uses asymmetric trimmed midpoint rather than median for the restoration of gray scale and color images that are heavily corrupted by salt and pepper noise is proposed. The processed pixel is checked for 0 or 255; if examined pixel is equal to 0 or 255, then it is considered as noisy pixel(More)
A Decision based scheme using a improved mesh based snake like sorting is proposed for the restoration of gray scale images that are heavily corrupted by salt and pepper noise. The proposed algorithm uses modified mean or median for image restoration. The processed pixel is examined for 0 or 255; if checked pixel is equal to 0 or 255, then it is considered(More)
A Threshold based fixed 3x3 Non linear filter for the removal of image artifact such as blotches, black band noise, streaks and impulse is proposed. The algorithm detects the corrupted pixel, if the absolute difference between the processed pixel and the unsymmetrical trimmed midpoint is greater than a fixed threshold else termed as non noisy. Under high(More)
