A New Variational Model for Segmenting Objects of Interest from Color Images

Figure 4

An example of an image segmentation. (a) The original image (our desired objects are the yellow leaves). (b–c) The final active contour and 𝑢 obtained by using our model (𝑚=7, 𝛿𝑡=1/8, 𝜆_𝑖1=𝜆_𝑖2=0.001(𝑖=1,2,3), 𝜃=0.1). (d) The final active contour obtained by using the model in [23].
