Adaptive snakes: control of damping and material parameters
Ramin Samadani · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1991
The stability of active contour models or 'snakes' is studied. It is shown that the modification of snake parameters using adaptive systems improves both the stability of the snakes and the boundaries obtained. The adaptive snakes perform better with images of varying contrasts, noisy images, and images with different curvatures along the boundaries. The computational costs at each iteration for the adaptive snakes is still of order (Nu) , where (Nu) is the number of points on the snakes. Comparisons of the results for non-adaptive and adaptive snakes are shown using both computer simulations and satellite images.
