Abstract

Two new adaptive active contour algorithms for the extraction and mapping of the skeleton of a thick curve are described. They are based on conditions which guarantee uniqueness and fidelity of the solution. Both algorithms modify the regularization constant K/sub o/ in an attempt to maintain convexity of the energy function while simultaneously improving the fidelity of the result. The first algorithm changes K/sub o/ over time while the second adapts K/sub o/ spatially. Both algorithms are evaluated on experiments with synthetic curves; both demonstrate an improved performance compared to a fixed-parameter active contour algorithm.<>
