ABSTRACT

Digital Cameras which capture images in directly in digital form. Digital Images are mostly often corrupted by impulse noises. It is affected by sharp & characteristics of the image signal. So the image processing scheme should be one of the important part in any vision application permitting to suppress noise& improve the image performances without any noises. This demands to have several filtering schemes such as fuzzy & non-fuzzy are used. In this paper, propose 3 step fuzzy filter is used to remove the impulse noise. Fuzzy based filters are the best and efficient filters in the sense of reduced mean square error (MSE) and high PSNR (peak signal to noise ratio) between the original and recovered signal.
