Scale-Space Processing of Point-Sampled Geometry for Efficient 3D Object Segmentation [PDF]

open access: yesIEICE Transactions on Information and Systems, 2004
In this paper, we present a new framework for analyzing and segmenting point-sampled 3D objects. Our method first computes for each surface point the surface curvature distribution by applying the principal component analysis on local neighborhoods with different sizes.
