Using mathematical morphology for similarity search of 3d objects

R Lam, JM Hans du Buf - Pattern Recognition and Image Analysis: 5th …, 2011 - Springer
In this paper we use the erosion and dilation operators for characterizing 3D polygonal
objects. The goal is to perform a similarity search in a set of distinct objects. The method …

Retrieval of 3D polygonal objects based on multiresolution signatures

R Lam, JMH Du Buf - International Symposium on Visual Computing, 2011 - Springer
In this paper we present a method for retrieving 3D polygonal objects by using two sets of
multiresolution signatures. Both sets are based on the progressive elimination of object's …
