Modelling of irregularly sampled surfaces by two-dimensional snakes
Abstract A new method for the modelling of irregularly sampled surfaces is presented. The surfaces under consideration allow discontinuities of the first and higher derivatives. The method discussed is a generalization of the so called snakes approximation method. The variational problem, which is part of the snakes modelling, turns out to be the weighted sum of a membrane and a thin-plate-spline kernel. The variational problem is solved by the direct method using scaled and shifted Gaussians as base functions. The efficiency of the proposed method is demonstrated for a set of laser-scanning data.
