The Ovuscule
—We propose an active contour (a.k.a. snake) that takes the shape of an ellipse. Its evolution is driven by surface terms made of two contributions: the integral of the data over...

Eigensnakes for Vessel Segmentation in Angiography
In this paper we introduce a new deformable model, called eigensnake, for segmentation of elongated structures in a probabilistic framework. Instead of snake attraction by speci...

Simulated Static Electric Field (SSEF) Snake for Deformable Models
In this paper, a novel design of external force for snake is proposed. This kind of external force is actually a field, which we call the Simulated Static Electric Field (SSEF). T...

Curvature Vector Flow to Assure Convergent Deformable Models for Shape Modelling
Poor convergence to concave shapes is a main limitation of snakes as a standard segmentation and shape modelling technique. The gradient of the external energy of the snake represe...
