Shivering Greedy Snakes Gradient-Guided in Wavelet Domain (original) (raw)

1998

Abstract

The convergence speed of snakes is increased with the switching step size of local minima search and they are incorporated with the local gradient information in the wavelet domain to provide extra speed of convergence to their final contours. This is important in model based compression applications using wavelet decomposition. The directional gradient information is extracted from the subbands provided
