11. A comparison of methods for sketch-based 3D shape retrieval
Topic: Imaging
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 ...

12. An Empirical Study of Sample Size in ROC-Curve Analysis of Fingerprint Data
Topic: Imaging
Published: 12/4/2006
Authors: Jin Chu Wu, Charles Wilson
Abstract: The fingerprint datasets in many cases may exceed millions of samples. Thus, the needed size of a biometric evaluation test sample is an important issue in terms of both accuracy and efficiency. In this article, an empirical study, namely, using Ch ...

13. An Evaluation of Local Shape Descriptors for 3D Shape Retrieval
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7812
Topic: Imaging
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 ...

14. An Exploration of the Operational Ramifications of Lossless Compression of 1000 ppi Fingerprint Imagery
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7779
Topic: Imaging
Published: 8/6/2012
Authors: Shahram Orandi, John M Libert, John Donald Grantham, Kenneth Ko, Stephen S Wood, Jin Chu Wu, Lindsay M. Petersen, Bruce Bandini
Abstract: This paper presents the findings of a study initially conducted to measure the operational impact of JPEG 2000 lossy compression on 1000 ppi fingerprint imagery at various levels of compression, but later expanded to include lossless compression. Los ...

15. An Inexpensive Video Signal Multiplexer for Multi-Camera Machine Vision in Automated Analytical Laboratory Systems
Topic: Imaging
Published: 12/7/1998
Authors: Gary W Kramer, P J Grandsard
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=902159

16. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Imaging
Published: 9/26/2012
Authors: Afzal A Godil, Sarah Y. Tang
Abstract: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. A common approach is to calculate a shape descriptor for each object, which can then be compared to determine two objects‰ similarity. H ...

17. Automated Extraction of Cellular Features for a Potentially Robust Classification Scheme
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7738
Topic: Imaging
Published: 1/19/2011
Authors: Afzal A Godil, Shwetadwip Chowdhury
Abstract: The advent of new imaging technologies has allowed faster and higher-resolution cellular image acquisition by light microscopy. This has directly aided clinical research by allowing doctors and other researchers to better visualize cells and cellula ...

18. Benchmarks, Performance Evaluation and Contests for 3D Shape Retrieval
Topic: Imaging
Published: 12/20/2010
Authors: Afzal A Godil, Zhouhui Lian, Helin Dutagaci
Abstract: Benchmarking of 3D Shape retrieval allows developers and researchers to compare the strengths of different algorithms on a standard dataset. Here we discuss the different steps involved in developing a benchmark and some of the issues involved. We th ...
