1 October 1998 Sandwich snakes: robust active contours
Author Affiliations +
Snakes are active contours that minimize an energy function. Sandwich snakes are formed by two snakes, one inside and the other outside of the contour that one is looking for. They have the same number of particles, which are connected in correspondence one to one. At the global minimum the two snakes have the same position.
