Segmentation et modélisation 3D par un ensemble de superellipsoïdes

Abstract : In this article we propose a innovative model to represent a non organised 3D points set. Based on superquadrics, this model permits to describe the points set with a superellipsoid union. Two different methodologies are developed for segmenting and modelling the whole representation: a Region Growing and a Split and Merge one. This latter provides a low sensitive model compared to the first method. The representation is simple and compact, as only 11 parameters are required per superellipsoid. This seems promising to be used for applications such as 3D compression, or even 3D indexing and retrieval. While the relationship between superellipsoids is known, the model could be associated to a graph. Yet, graph theory can be used to compare and measure similarities between 3D objects.
