The trend in modern image noise filtering algorithms has been toward structure preservation by using only those neighbouring pixels which are similar to the current pixel in some way. In this paper we introduce a technique, call FUELS (filtering using explicit local segmentation), which explicitly segments the m × m region encompassing the current pixel and filters using only those pixels from the same segment. By exploiting mask overlap an effective mask size of(2m-1)×(2m-1) is obtained, as well as robustness in regions which do not fit the image model. The algorithm can be iterated, and our results show FUELS to outperform existing algorithms both quantitatively and qualitatively
