Image Smoothing and Denoising with Segment Bilateral Filter

Abstract

A modified window bilateral filter has been developed. Its denoising capability is superior to that of the bilateral filter. In this letter, we describe how the modified window bilateral filter, called the segment bilateral filter, evalutaes the similarity between pixels with selected pixels belonging to the same segment as the target pixel. Experiments demonstrated that the segment bilateral filter preserves object contours and removes noises in images better than the window biltaeral filter.
