1. Shape Retrieval of Non-Rigid 3D Human Models
Topic: Data and Informatics
Published: 4/26/2016
Authors: Afzal A Godil, David Pickup
Abstract: 3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between body shapes is an important shape retrieval problem. We extend our recent paper which provided a benchmark for testing non-rigid ...

4. SHREC‰14 Track: Shape Retrieval of Non-Rigid 3D Human Models
Topic: Data and Informatics
Published: 6/12/2014
Authors: Afzal A Godil, Chunyuan Li
Abstract: We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body shapes and poses. 3D model ...

5. A comparison of methods for sketch-based 3D shape retrieval
Topic: Data and Informatics
Published: 12/13/2013
Author: Afzal A Godil
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. To foster this research area, two Shape Retrieval Contest (SHREC) tracks on this topic have been organized by us in 2012 and 2013 based on ...

6. Terabyte Size Image Computations on Hadoop Cluster Platforms
Topic: Data and Informatics
Published: 10/7/2013
Authors: Peter Bajcsy, Antoine Vandecreme, Julien M. Amelot, Phuong Thi Thu Nguyen, Joe Chalfoun, Mary C Brady
Abstract: We present a characterization of four basic terabyte size image computations on a Hadoop cluster in terms of their relative efficiency according to the modified Amdahl‰s law. The work is motivated by the fact that there is a lack of standard benchmar ...

7. Significance Test with Data Dependency in Speaker Recognition Evaluation
Topic: Data and Informatics
Published: 7/25/2013
Authors: Jin Chu Wu, Alvin Frank Martin, Craig Stuart Greenberg, Raghu N Kacker, Vincent M Stanford
Abstract: To evaluate the performance of speaker recognition systems, a detection cost function defined as a weighted sum of the probabilities of type I and type II errors is employed. The speaker datasets may have data dependency due to multiple uses of the s ...

8. Data Quality for High Content Screening
Topic: Data and Informatics
Published: 9/3/2012
Authors: YaShian Li-Baboud, Oleg Aulov, Peter Bajcsy
Abstract: TO HAVE CONFIDENCE IN THE KNOWLEDGE GLEANED FROM DATA, IT IS ESSENTIAL TO VERIFY THE QUALITY OF THE DATA SOURCES AND TO HAVE A MEANS OF QUANTIFYING THE POTENTIAL UNCERTAINTIES DUE TO THE QUALITY OF DATA FOR MAKING CRITICAL, INTELLIGENT DECISIONS. ...

9. SHREC‰12 Track: Generic 3D Shape Retrieval
Topic: Data and Informatics
Published: 5/13/2012
Authors: Bo Li, Afzal A Godil
Abstract: Generic 3D shape retrieval is a fundamental research area in the field of content-based 3D model retrieval. The aim of this track is to measure and compare the performance of generic 3D shape retrieval methods implemented by different participant ...

10. An Evaluation of Local Shape Descriptors for 3D Shape Retrieval
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7812
Topic: Data and Informatics
Published: 3/8/2012
Author: Sarah Y. Tang
Abstract: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. Most prominently, shape descriptors are used to describe the geometric and topological properties of objects and compared to determine t ...
