Surface Evolution Based on Wave Propagation and Its Application to Topology-Adaptive 3D Modeling

Deformable surfaces have been successfully used for modeling 3-D objects. However, they have not been able to model multi-object scenes or objects with holes. In the paper, we propose a new method of modeling objects of arbitrary topology by using a surface evolution approach based on wavefront propagation. Differing from level set modeling methods, we do not require repeated distance transformations and increased dimensions, and hence the method is computationally efficient. The method has been applied in several experiments using range data, and the results are reported in the paper.
