Figure 4From: A new model for segmentation of gray-scale and color imagesSegmentation of a noisy color image. (a) The noisy image. (b) and (c) The final active contour and u obtained by using our new model (θ=0.1, β=50/ 255 2 , δt=1/8, σ=5, λ i 1 = λ i 2 =0.0003, i=1,2,3, iteration times=100).Back to article page
