Digital Images are generally corrupted by noise, Noise is nothing but addition of unwanted information for the Original Image. Removal of the noise is necessary to reduce the minimal damage of the image, improve image details. Contourlet transform is employed with the directional filter bank to capture the discontinuities of line and it gives various directional decomposition.ABC algorithm is bio-inspired algorithm which is derived from intelligent food search nature of the honey bee. ABC as an optimization tool provides a population-based search procedure in which individuals called foods positions are modified by the artificial bees with time and the bee’s aim is to discover the places of food sources with high nectar amount and finally the one with the highest nectar. The hard thresholding will kill all the coefficients whose magnitudes are less than the threshold to zero while keeping the remaining coefficients unchanged. Contourlet with image denoising with ABC optimization based hard thresholding it improves the image quality.
