Description: The t raditional snake initial contour should be close to the t rue boundary of interested ob2
ject in an image , or else it would converge to the wrong result . Next , active contours have difficulties
progressing into boundary concavities. Moreover , the t raditional snake and it s almost kinds of im2
proved methods are easy to get into local minimum because snake models are non2convex. An active
contour model based on force field analysis , namely FFASnake model , is presented in this paper.
Based on analyzing force dist ribution rules of distance potential force field , a standard is int roduced
here to distinguish the false one f rom contour point s.
