Figure 3From: Fast two-phase image segmentation based on diffusion equations and gray level setsSegmentations for the noise Test01 image (size: 512×512). (a) The original image. (b) Corrupted Test01 image with Gaussian noise (σ=40). (c) Smoothed Test01 image with the AOS scheme (τ=70, α=0.7, twice iterations). (d) Algorithm DE-GLS. (e) Algorithm GLF-GLS. (f) CVM. (g)-(i) The segmentation counter of Algorithm DE-GLS, Algorithm GLF-GLS and CVM, respectively.Back to article page
