Segmentations for the noise Star image. (a) The original image. (b) Smoothed Star image with the numerical scheme (23) (𝜆=0.1 and 3 steps). (c) Smoothed Star image (𝜆=0.1 and 10 steps). (d)–(g) Segmentation for the original image by Algorithms 7 and 1, respectively. (h)–(k) The segmentation for the smooth image (b). (l)–(o) The segmentation for the smooth image (c).
