@ALDAOperator(genericExecutionMode=ALL) @ALDDerivedClass public class SnakeOptimizerSingleGreedy extends SnakeOptimizerSingle
Image contour segmentation using parametric snakes with greedy optimization. This class provides methods to segment contours in an image based on parametric active contour models, i.e. snakes. The snake optimization is done based on a greedy algorithm. Its main intention is for comparison and demontration purposes. You should always keep in mind that greedy snake algorithms are slow - particularly since for each point movement excessive local energy calculations have to be done.
