1. An evaluation of local shape descriptors for 3D shape retrieval
Topic: Software
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 ...

2. Review: Biological Imaging Software Tools
Topic: Software
Published: 8/29/2012
Authors: Anne L Plant, Kevin Eliceiri, Anne Carpenter
Abstract: Few technologies are more widespread in modern biological laboratories than imaging by microscopy. Advancements in optical technologies and instrumentation over the past twenty years have led to massive improvements in the resolution, specificity, d ...

3. Feature-preserved 3D Canonical Form
Topic: Software
Published: 7/28/2012
Authors: Afzal A Godil, Zhouhui Lian
Abstract: 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 domain) on ...

4. Evaluation of 3D Interest Point Detection Techniques via Human-generated Ground Truth
Topic: Software
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 ...

5. A New Convexity Measurement for 3D Meshes
Topic: Software
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 ...

7. A Comparison of hp-adaptive Strategies for Elliptic Partial Differential Equations (long version)
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7824
Topic: Software
Published: 10/5/2011
Authors: William F Mitchell, Marjorie A McClain
Abstract: The hp version of the finite element method (hp-FEM) combined with adaptive mesh refinement is a particularly efficient method for solving partial differential equations because it can achieve a convergence rate that is exponential in the number ...

8. Salient Local 3D Features for 3D Shape Retrieval
Topic: Software
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 ...
