This paper presents a novel classification strategy for 3D objects. Our technique is based on using a Global Geodesic Function to intrinsically describe the surface ofan object. The choice of the Global Geodesic Function ensures the invariance ofthe classification procedure to scaling and all isometric transformations. Using the Jensen-Shannon Divergence, feature parameters are extracted from the probability distribution functions of the Global Geodesic Function for each one ofthe classes. These parameters are used in the decision of a class membership of an object. This approach demonstrates low computational cost, efficiency, and robustness to resolution over many different data sets.
