1. 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 ...

2. 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 ...

3. A New Convexity Measurement for 3D Meshes
Topic: Data Mining
Published: 6/16/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: This paper presents a novel convexity measurement for 3D meshes. The new convexity measure is calculated by minimizing the ratio of the summed area of valid regions in a mesh’s six views, which are projected on faces of the bounding box whose edg ...

4. A comparison of methods for Non-rigid 3D shape retrieval
Topic: Data Mining
Published: 9/26/2012
Authors: Zhouhui Lian, Afzal A Godil
Abstract: Non-rigid 3D shape retrieval has become an active and important research topic in content-based 3D object retrieval. The aim of this paper is to measure and compare the performance of state-of-the-art methods for non-rigid 3D shape retrieval. The pa ...

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

6. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Data Mining
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 ...

7. 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 ...

9. Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth
Topic: Data Mining
Published: 6/29/2012
Authors: Afzal A Godil, Helin Dutagaci
Abstract: In this paper, we present an evaluation strategy based on human-generated ground truth to measure the performance of 3D interest point detection techniques. We provide quantitative evaluation measures that relate automatically detected interest point ...

10. 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 ...
