1. A method for smoothing digital images, comprising operating on an original source image, I, comprising pixel values p(i, j) at respective pixel locations (i, j), to produce a smoothed image, I smoothed , comprising pixel values P smoothed (i, j) at respective pixel locations (i, j), wherein for each pixel location (i, j) the smoothed pixel value P smoothed (i, j) is computed as a weighted average of the corresponding pixel value p(i, j) with at least one pixel window average of I.
