In digital Image Processing, removal of noise is a highly demanded area of research. Impulsive noise is common in images which arise at the time of image acquisition and or transmission of images. In this paper, a new hybrid filtering algorithm is presented for the removal of impulse noise from digital images. Here, we replace the impulse noise corrupted pixel by the median of the pixel scanned in four directions. The experimental results of this filter applied on various images corrupted with almost all ratios of impulse noise favor the filter in terms of objectivity than many of the other prominent impulse noise filters.
