| Abstract: | Noise free images are projected for good understanding of the data present in it. But due to many factors noise gets added and corrupts the image quality. Images are mainly affected by noise when they are transmitted over the unsecure channels. Mostly the images are infected by impulse noise due to faulty communications. Various filters are applied to make the images noise free in order to achieve the images with no or minimum signal distortion. Median filters are best suited digital on linear filters to remove the impulse noise from the images while preserved the edges of the images. In contrast to the unadventurous median filters, a decision based median filter is applied to detect the noisy pixels so that filter is applied only to the corrupted pixels thereby preserved the image features and leaving the uncorrupted pixels unscratched. In this paper we have presented a novel unsymmetrical trimmed median filter for removing the noise and to restore the Gray scaled and coloured images highly infected by impulse noise. A decision based filter first figures out the noisy pixels and then changes them by median value if other than 0 and 255values are present in the particular window and change the noisy pixels by the mean value of all the elements in the selected window if only 0’s and 255’s are present. The proposed algorithm is tested against different gray scaled and coloured images. |
