Distribution distance measures applied to 3-D object recognition - A case study

Abstract

In this paper we analyse dissimilarity measures for probability distributions which are frequently used in the area of pattern recognition, image processing, -indexing and registration, amongst others. Namely χ2, Jenson-Shannon divergence, Fidelity and Trace are discussed. We use those measures to tackle the task of recognising three dimensional objects from two dimensional images. The object reference model is defined by (several) feature distributions derived from multiple two dimensional views of each object. The experiments performed on the Columbia Object Image Library indicate that derivatives of Fidelity used as distance measures perform well in terms of recognition rate. If enough views can be provided for modelling (roughly one view per 20°-30°), up to a 100% recognition rate is achievable. © Springer-Verlag Berlin Heidelberg 2003.
