Abstract
In this paper an effort has been made to device an algorithm for highly corrupted images. In this paper a novel Modified Weighted Based(MWB) filter has been proposed, which is based on the weighted differences between the current pixel and its neighbors aligned with four main directions. Simulations showed that the MWB filter provides optimal performances of suppressing impulse with high noise level which may enhance the performance in terms of removal of random-valued impulse noise compared to the directional weighted median (DWM) filter [1] along with other filters like signal-dependent rank order mean (SDROM)filter[6], multistate median (MSM) filter[2], adaptive center weighted median (ACWM) filter[8], pixel-wise MAD(PWMAD) filter[7] etc.
