Automatic Segmentation of Optic Disc and Cup in Retinal Fundus Images Using Improved Two-Layer Level Set Method

Figure 3

The comparison of the evolution process of level set functions in different methods. (a) The experimental results of the proposed method without prior elliptic shape constraint term. (b) The experimental results of the proposed method. From top to bottom in the figure are 100 iterations, 200 iterations, 300 iterations, and final results.
