Abstract. In this paper we describe our 3D object signature for 3D
object classification. The signature is based on a learning approach that
finds salient points on a 3D object and represent these points in a 2D
spatial map based on a longitude-latitude transformation. Experimen-
tal results show high classification rates on both pose-normalized and
rotated objects and include a study on classification accuracy as a func-
tion of number of rotations in the training set.
Key words: 3D Object Classification, 3D Object Signature
1 Introduction
Advancement in technology for digital acquisition of 3D models has led to an
increase in the number of 3D objects available in specific application databases
and across the World Wide Web. This has motivated recent research in two
major areas. The first research area is 3D object retrieval where the goal is to
retrieve 3D objects from a database that are similar in shape to a given 3D
