Abstract
A cross-entropy method for the classification of 3D objects with curved sur faces is proposed. Tn the proposed approach. small. cross-entropy between t he shape histograms of two objects indicates that the two objects are simil ar, where the shape histogram is defined as the distribution of the shape i ndices computed at pixels on the object. Experiments with real rang images show that the cross-entropy method can he used to classify 3D objects with curved surfaces.
