A fast and flexible multiresolution snake with a definite termination criterion

This paper describes a fast process of parametric snake evolution with a multiresolution strategy. Conventional parametric evolution method relies on matrix inversion throughout the iteration intermittently, in contrast the proposed method relaxes the matrix inversion which is costly and time consuming in cases where the resulting snake is exible. The proposed method also eliminates the input of snake rigidity parameters when the snake is exible. Also a robust and de nite termination criterion for both conventional and proposed methods is demonstrated in this paper.
