Paper Abstract:	Energy minimizing contours, known as snakes, are tools for segmentation of objects of interest in an image. Snakes can be defined either as discrete points or continuous parametric curves. R-snakes belong to the latter group and are based on parametric rational Gaussian curves. Their formulation allows for continuous local and/or global variation of the contour’s stiffness, which enables an R-snake to adjust to boundaries of smooth or detailed objects. That property is used in an application for interactive segmentation of tumors from Micro Computed Tomography (Micro-CT) volumes and experimental results are presented.
