The annual SHape REtrieval Contest (SHREC) measures the performance of 3D model retrieval methods for several different types of models and retrieval purposes. In this contest the structural shape retrieval track focuses on the retrieval of 3d models which

SHREC 2009 - Shape Retrieval Contest of Partial 3D Models

March 29, 2009
Author(s)
Helin Dutagaci, Afzal A. Godil, A. Axenopoulos, P. Daras, T. Furuya, R. Ohbuchi
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

Afzal A. Godil, Chun Pan (Benny) Cheung, Asim Wagan, Xiaolan Li
Bio-imaging toolkit is an application for biological imaging community that will bring in the latest efforts in indexing, searching, navigation, discovery, analysis and annotation for both biological image and video collections. This paper discusses both

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

Shape and Size Analysis and Standards

October 6, 2008
Author(s)
Afzal A. Godil, Sanford P. Ressler
The field of anthropometry is the science of measurement of the human body from which comparisons and characterizations of the size and shape of the body in different postures can take place. The size and shape of human bodies are important in many
