Non Linear Filter Design in Spatial Domain for High Density Impulse Noise Removal
Battula Srinivasa Rao, K. Srinivas · 2012
A spatial domain non linear filtering algorithm for the restoration of gray scale, and Color images that are corrupted by high density impulse noise is proposed. The proposed algorithm well suited for suppressing impulse and also Gaussian noises with different noise leves.It shows better results than the Standard Median Filter (MF), Trimmed Median Filter (TMF) and Weighted Median Filter. Experiment Result shows the proposed algorithm has advantages over regularizing methods in terms of both edge preservation and noise removal and it gives the better Peak Signal to Noise Ratio (PSNR) compared to other techniques even in the high noise densities.
