Abstract
We address the problem of inferring integrated high-level descriptions such as surfaces, 3D curves, and junctions from a sparse point set. For precise localization, we propose a noniterative cooperative algorithm in which surfaces, curves, and junctions work together. Initial estimates are computed based on the work by Guy and Medioni (1997), where each point in the given sparse and possibly noisy point set is convolved with a predefined vector mask to produce dense saliency maps. These maps serve as input to our novel extremal surface and curve algorithms for initial surface and curve extraction. These initial features are refined and integrated by using excitatory and inhibitory fields. Consequently, intersecting surfaces (resp. curves) are fused precisely at their intersection curves (resp. junctions). Results on several synthetic as well as real data sets are presented.Keywords
