Failure of the proposed method. The level set function is initialized using the function in Figure 8 for the first two images. Final level set contours based on the proposed method using heat equation as a potential function (a), final level set contours based on the proposed method using the potential function P ₂ without preprocessing (b), binary mask for initialization of the level set function (c), and final level set contours based on the proposed method using the potential function P ₂ (d).
