ABSTRACT

This Paper presents highly efficient two phase schema for removing impulse noise. In the first phase, robust algorithm for noise detection is used to identify noisy pixels. In the second phase, the image is restored using special noise control algorithm. Efficiency of algorithm is tested by comparing with most powerful AMF (Adaptive Median Filter), DBA (Decision Based algorithm) and MTND (Median Type Noise Detector). An experimental result shows that the proposed algorithm works efficiently up to 99% of noise ratio.
