The External Forces of Image Segmentation Using Deformable Model

ZU Ke-ju,ZHOU Chang-xiong (School of Electronics and Information Jiangsu University of Science and Technology Zhenjiang, Jiangsu, 212003)  
Deformable model is an effective method in image segmentation. The external forces of deformable model have significant effect on segmentation, and are researched extensively. This paper introduces some typical external forces: Gaussian potential force, Distance potential force, Gradient vector flow, develops the energy functional and force balance equation of electrostatic active contour model (eSnake). Experimentally, the external force fields of different forces are compared. It can be seen that the electrostatic force has clear physical meaning, and is simple to implementation, reliable for shape segmentation while having larger capture range for external force, the stronger ability to conform to boundary concavities. Electrostatic model has the strong ability to avoid snake curve being trapped by the noise points or spurious edges.
