Figure 2From: A new model for segmentation of gray-scale and color imagesSegmentation of the image of a liver. (a) The original image. (b) The result obtained by using the model in [11]. (c) and (d) The final active contour and u obtained by using our new model (θ=0.1, β=50/ 255 2 , δt=1/8, σ=2, λ 11 = λ 12 =0.001, iteration times=100).Back to article page
