1. A method for processing a digital image, the method comprising: estimating a foreground region relating to an imaged object; estimating a background region relating to other than the imaged object; and by using the image, the estimated foreground region and the estimated background region, calculating a transition region disposed between the foreground region and the background region; wherein the estimated foreground region, the estimated background region, and the calculated transition region, each comprise a separate set of pixels that may each be processed separately for suppressing pixel intensities in the estimated background region and improving image quality.
