Abstract
Active contours, and snakes in particular, are effective tools for image segmentation. Within an image, an active contour is a curve that evolves from an initial position, which is usually specified by a user, toward the boundary of an object. The evolution of the curve is formulated as a minimization problem. Snakes have become popular because it is possible for the user to interact with them, not only when specifying its initial position, but alsoduring the segmentation process. In this talk, we will revisit the framework of parametric snakes, showing how to design them for specific applications. We will pay special attention to the spline-based ones and show recent optimality results. Some work-in-progress will be shown in order to provide an idea of the current research challenges.
