In this paper, solution for very high density salt and pepper impulse noise is proposed. An algorithm is designed by considering the different parameters that influence the effect of noise reduction. The proposed algorithm contains two phases: Phase 1 detects the noisy pixels and Phase 2 replaces identified noisy pixels by non-noisy estimated values. Restored Mean Absolute Error (RMAE) is used to measure and compare the performance of the proposed algorithm. The algorithm is compared with several non-linear algorithms reported in the literature. Experimental results show that the proposed algorithm produces better results compared to the existing algorithms.
