In our proposed scheme restoratiom or denoising of gray scale and video images that are greatly corrupted by severe impulse noise .our scheme works excellently by replacing every noise pixel by trimmed median value so that other situated pixel values, like zero’s (0’s) and 255’s so thereafter each noise pixel is immediately replaced by the increasing window size and finds trimmed mean among them based on algorithm mentioned. We also had comparative analysis over Standard Median Filter (SMF), Progressive Switched Median Filter (PSMF),Modified Decision Based Median Filter (MDBMF) and Modified Decision Based Unsymmetrical Trimmed Median Filter (MDBUTMF).We simulated above images and video by proposed algorithm on Matlab where we achieved better PSNR and less MSE and also good image enhancement factor(IEF).
