Retrieving articulated 3-D models using medial surfaces

K Siddiqi, J Zhang, D Macrini, A Shokoufandeh… - Machine vision and …, 2008‏ - Springer
We consider the use of medial surfaces to represent symmetries of 3-D objects. This allows
for a qualitative abstraction based on a directed acyclic graph of components and also a …

PANORAMA: A 3D shape descriptor based on panoramic views for unsupervised 3D object retrieval

P Papadakis, I Pratikakis, T Theoharis… - International Journal of …, 2010‏ - Springer
We present a novel 3D shape descriptor that uses a set of panoramic views of a 3D object
which describe the position and orientation of the object's surface in 3D space. We obtain a …

Efficient 3D shape matching and retrieval using a concrete radialized spherical projection representation

P Papadakis, I Pratikakis, S Perantonis, T Theoharis - Pattern Recognition, 2007‏ - Elsevier
