The objective of the SHREC 09 Shape Retrieval Contest of Partial Models is to compare the performances of algorithms that accept a range image as the query and retrieve relevant 3D models from a database. The use of a range scan as the query addresses a

SHREC'09 Track: Generic Shape Retrieval

March 29, 2009
Author(s)
Afzal A. Godil, Helin Dutagaci
In this paper we present the results of the SHREC 09- Generic Shape Retrieval Contest. The aim of this track was to evaluate the performances of various 3D shape retrieval algorithms on the NIST generic shape benchmark. We hope that the NIST shape

Onset of Oscillatory Convection in Two Liquid Layers with Phase Change

March 2, 2009
Author(s)
Geoffrey B. McFadden, Sam R. Coriell
We perform linear stability calculations for horizontal fluid bilayers that can undergo a phase transformation in the presence of a vertical temperature gradient. We reconsider the oscillatory instability calculated by Huang and Joseph [J. Fluid Mech. 242

Spatially Enhanced Bags of Words for 3D Shape Retrieval

December 3, 2008
Author(s)
Xiaolan Li, Afzal A. Godil, Asim Wagan
This paper presents a new method for 3D shape retrieval based on the bags-of-words model along with a weak spatial constraint. First, a two-pass sampling procedure is performed to extract the local shape descriptors, based on spin images, which are used to
