This is an icy package that encapsulates tools to design and implement parametric active contours. The package provides fast 2D and 3D filters for image preprocessing, and a framework to create and evolve snakes defined by a set of control points.
This software implements an active contour (a.k.a. snake) segmentation method using exponential splines as basis functions to represent the outline of the shape. While the snake is versatile enough to provide a good approximation of any closed curve in the plane, its most important feature is that it perfectly reproduces circular and elliptical shapes. These features are very appropriate to delineate cross sections of cylindrical-like conduits and to outline blob-like objects.
