ABSTRACT :
Today, it is increasingly frequent and easy to digitize the surface of real 3D
objects. However, the obtained meshes are often inaccurate and noisy. In this
paper, we present a method to analyze a curvature histogram from a digitized
3D surface using a real object. Moreover, we propose to use the curvature
histogram analysis for three distinct applications which are : the mesh segmen-
tation, the primitive type detection and the measure of quality. Experimental
results applied on real digitized 3D meshes show the eciency of our proposed
analysis.
