Illustration of the effectiveness of the weights calculated from neighboring windows. (a, d) Noisy image, (b, e) smoothing image using the difference between intensities, and (c, f) using neighboring windows. All other parameters are the same as in (b, e). (a) Noisy image, (b) intensity, (c) window, (d) noisy image, (e) intensity, and (f) window.
