11. Extracting Hierarchies With Overlapping Structure From Network Data
Topic: Data Mining
Published: 12/11/2011
Author: Brian Dale Cloteaux
Abstract: Relationships between entities in many complex systems, such as the Internet and social networks, have a natural hierarchical organization. Understanding these inherent hierarchies is essential for creating models of these systems. Thus, there is a r ...

12. Iris Quality Calibration and Evaluation (IQCE): Evaluation Report
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7820
Topic: Data Mining
Published: 9/24/2011
Authors: Elham Tabassi, Patrick J Grother, Wayne J Salamon
Abstract: Iris is rapidly gaining acceptance and support as a viable biometric. Several large scale identity management applications are either using or considering iris as their secondary or primary biometric for verification. While there are several academ ...

13. Toward Privacy Standards Based on Empirical Studies
Topic: Data Mining
Published: 4/28/2011
Authors: Serge M. (Serge) Egelman, Erika McCallister
Abstract: In this paper, we argue that if privacy standards are created to guide “do-not-track” technologies, it is imperative that these standards are created with the primary stakeholder in mind: the data subject. Previous privacy and security standards ha ...

14. A Feature-preserved Canonical Form for Non-rigid 3D Meshes
Topic: Data Mining
Published: 4/14/2011
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Measuring the dissimilarity between non-rigid objects is a challenging problem in 3D shape retrieval. One potential solution is to construct the models’ 3D canonical forms (i.e., isometry-invariant representations in 3D Euclidean space) on which any ...

15. Salient Local 3D Features for 3D Shape Retrieval
Topic: Data Mining
Published: 4/7/2011
Authors: Afzal A Godil, Asim Wagan
Abstract: In this paper we describe a new formulation for the 3D salient local features based on the voxel grid inspired by the Scale Invariant Feature Transform (SIFT). We use it to identify the salient keypoints (invariant points) on a 3D voxelized model and ...

16. Automated Extraction of Cellular Features for a Potentially Robust Classification Scheme
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7738
Topic: Data Mining
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 ...

17. NON-RIGID 3D SHAPE RETRIEVAL USING MULTIDIMENSIONAL SCALING AND BAG-OF-FEATURES
Topic: Data Mining
Published: 12/20/2010
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Matching non-rigid shapes is a challenging research field in content-based 3D object retrieval. In this paper, we present an image-based method to effectively address this problem. Multidimensional Scaling (MDS) and Principal Component Analysis ( ...

18. Investigating the Bag-of-Words Method for 3D Shape Retrieval
Topic: Data Mining
Published: 6/30/2010
Authors: Afzal A Godil, Xiaolan Li
Abstract: This paper investigates the capabilities of the Bag-of-Words (BW) method in the 3D shape retrieval field. The contributions of this paper are: 1) the 3D shape retrieval task is categorized from different points of view: specific vs. generic, part ...

19. 3D shape retrieval based on Multi-scale Integral Orientations
Topic: Data Mining
Published: 5/2/2010
Authors: Afzal A Godil, Stephane Bres, Asim Wagan
Abstract: In this paper we describe a novel 3D shape retrieval method based on Multi-scale Integral Orientations. In our approach, a 3D model after normalization is represented by a set of depth images captured uniformly on a unit circle. Then the shape descri ...

20. SHREC 10 Track: Generic 3D Warehouse
Topic: Data Mining
Published: 5/2/2010
Authors: Vanamali ThiruvadandamPorethi, Afzal A Godil, Helin Dutagaci, Zhouhui Lian, Ryutarou Ohbuchi, Takahiko Furuya
Abstract: In this paper we present the results of the Shape Retrieval Contest 10 (SHREC 10) of Generic 3D Warehouse. The aim of this track was to evaluate the performances of various 3D shape retrieval algorithms on a large Generic benchmark based on the Goo ...
