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. Exploring Local Features and the Bag-of-Visual-Words Approach for BioImage Classification
Topic: Imaging
Published: 11/5/2013
Authors: Afzal A Godil, Asim Wagan
Abstract: With recent advances in imaging technologies large numbers of bioimages are currently being acquired. Automated classification of these bio-images is a very important and challenging problem. Here we investigate the capabilities of local features a ...

13. Three-dimensional deep sub-wavelength defect detection using (lambda) = 193 nm optical microscopy
Topic: Imaging
Published: 10/25/2013
Authors: Bryan M Barnes, Martin Y Sohn, Francois R. Goasmat, Hui Zhou, Andras Vladar, Richard M Silver, Abraham Arceo
Abstract: Identifying defects in photolithographic patterning is a persistent challenge in semiconductor manufacturing. Well-established optical methods in current use are jeopardized by upcoming sub-20 nm device dimensions. Volumetric processing of focus-reso ...

14. Re-projection of Terabyte-Sized Images
Topic: Imaging
Published: 10/7/2013
Authors: Peter Bajcsy, Antoine Vandecreme, Mary C Brady
Abstract: This work addresses the problem of re-projecting a terabyte-sized 3D data set represented as a set of 2D Deep Zoom pyramids. In general, a re-projection for small 3D data sets is executed directly in RAM. However, RAM becomes a limiting factor for te ...

15. Terabyte Size Image Computations on Hadoop Cluster Platforms
Topic: Imaging
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 ...

16. Hybrid shape descriptor and meta similarity generation for non-rigid and partial 3D model retrieval
Topic: Imaging
Published: 7/26/2013
Author: Afzal A Godil
Abstract: Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alone ...

17. Non-Rigid and Partial 3D Model Retrieval Using Hybrid Shape Descriptor and Meta Similarity
Topic: Imaging
Published: 7/26/2013
Authors: Bo Li, Afzal A Godil, Henry Johan
Abstract: Non-rigid and partial 3D model retrieval are two significant and challenging research directions in the field of 3D model retrieval. Little work has been done in proposing a hybrid shape descriptor that works for both retrieval scenarios, let alo ...

18. Shape Calculus for Shape Energies in Image Processing
Topic: Imaging
Published: 7/22/2013
Authors: Gunay Dogan, Ricardo H. Nochetto
Abstract: Many image processing problems are naturally expressed as energy minimization or shape optimization problems, in which the free variable is a shape, such as a curve in 2d or a surface in 3d. Examples are image segmentation, multiview stereo reconstru ...

19. CM-BOF: Visual Similarity based 3D Shape Retrieval Using Clock Matching and Bag-of-Features
Topic: Imaging
Published: 6/6/2013
Authors: Afzal A Godil, Zhouhui Lian
Abstract: Content-based 3D object retrieval has be- come an active topic in many research communities. In this paper, we propose a novel visual similarity based 3Dshaperetrievalmethod(CM-BOF)usingClockMatch- ing and Bag-of-Features. Specifically, pose normal ...

20. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Imaging
Published: 6/6/2013
Authors: Afzal A Godil, Bo Li , Yijuan Lu, Tobias Schreck
Abstract: Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of sketch-based 3D shape retrieval methods based on a large scale hand-draw ...
