A New Deformable Model Using Dynamic Gradient Vector Flow and Adaptive Balloon Forces

An extension of the gradient vector flow snake (GVF snake) is presented. The method is based on combining two other external forces. First, the adaptive balloon force has been developed to increase the GVF snake’s capture range and convergence speed. Then, a dynamic GVF force is introduced to provide an efficient evolution-stop mechanism. In this way, we prevent the snake from breaking through the correct surface and locking to other salient feature points. Preliminary segmentation results demonstrate the potential of our approach in comparison with the original GVF snake
