A survey of methods for 3D model feature extraction

Hlavaty T., Skala V.

Journal Biuletyn of Polish Society for Geometry and Engineering Graphics

2003

Vol. 13

5--8

This paper deals with problems that are related to a feature extraction from 3D objects. The main aim of the feature extraction is to describe a shape of 3D object by a feature vector. Then the elements of this feature vector characterize the shape of the own 3D objects and they can serve as a key in searching for similar models. In this paper are introduced current methods for the feature extraction of 3D models and their classification. These methods are based on different mathematical background and according to that they are separated into several groups.
