Combination of adaptive median filter with ACO for eliminating the impulsive noise from colour images

—In this research paper, we proposed an ACO with a versatile for vector middle channel for the expulsion of motivation commotion from shading pictures. Regularly, the homogeneousness among the pixels is adulterated, when motivation clamor extraordinarily contorted the pictures. In the proposed method, just when the sifting activity will be done if the pixel is observed to be ruined. The choice about a specific pixel of being undermined or not relies upon the straight forecast blunder figured from the non-causal locale around the pixel under operation. Versatile window based vector middle separating activity will be done, if the mistake of the center pixel of the bit outperforms the officially characterized limit esteem. The span of versatile window will rely upon the level of blunder as indicated by the effectively characterized limit esteem. The proposed sifting system in charge of enhancing the pinnacle flag to clamor proportion (PSNR).
