41. 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 ...

42. SHREC‰14 Track: Extended Large Scale Sketch-Based 3D Shape Retrieval
Topic: Imaging
Published: 6/12/2014
Authors: Afzal A Godil, Chunyuan Li
Abstract: Large scale sketch-based 3D shape retrieval has received more and more attentions in the community of content- based 3D object retrieval. The objective of this track is to evaluate the performance of different sketch-based 3D model retrieval algori ...

43. SHREC‰14 Track: Large Scale Comprehensive 3D Shape Retrieval
Topic: Imaging
Published: 6/12/2014
Authors: Afzal A Godil, Chunyuan Li
Abstract: The objective of this track is to evaluate the performance of 3D shape retrieval approaches on a large-sale com- prehensive 3D shape database which contains different types of models, such as generic, articulated, CAD and architecture models. The t ...

44. SHREC‰14 Track: Retrieval and classification on Textured 3D Models
Topic: Imaging
Published: 6/12/2014
Author: Afzal A Godil
Abstract: This contribution reports the results of the SHREC 2014 track: Retrieval and classification on textured 3D models, whose goal is to evaluate the performance of retrieval algorithms when models vary either by geometric shape or texture, or both. The ...

45. SHREC‰14 Track: Shape Retrieval of Non-Rigid 3D Human Models
Topic: Imaging
Published: 6/12/2014
Authors: Afzal A Godil, Chunyuan Li
Abstract: We have created a new benchmarking dataset for testing non-rigid 3D shape retrieval algorithms, one that is much more challenging than existing datasets. Our dataset features exclusively human models, in a variety of body shapes and poses. 3D model ...

46. Salient Local 3D Features for 3D Shape Retrieval
Topic: Imaging
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 ...

47. 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 ...

48. Shape Retrieval of Non-Rigid 3D Human Models
Topic: Imaging
Published: 4/26/2016
Authors: Afzal A Godil, David Pickup
Abstract: 3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between body shapes is an important shape retrieval problem. We extend our recent paper which provided a benchmark for testing non-rigid ...

49. Survey Statistics of Automated Segmentations Applied to Optical Imaging of Mammalian Cells
Topic: Imaging
Published: 1/8/2016
Authors: Peter Bajcsy, Antonio Cardone, Joe Chalfoun, Michael W Halter, Derek Juba, Marcin Kociolek, Michael P Majurski, Adele P Peskin, Carl George Simon Jr., Mylene Henriqueta Monique Simon, Antoine Vandecreme, Anne L Plant, Mary C Brady
Abstract: The goal of this survey paper is to overview cellular measurements using optical microscopy imaging followed by automated image segmentation. The cellular measurements of primary interest are taken from mammalian cells and their components. They are ...

50. TRECVid Semantic Indexing of Video: A 6-Year Retrospective
Topic: Imaging
Published: 7/1/2016
Authors: George Morad Awad, Cees Snoek, Alan Smeaton, Georges Quenot
Abstract: Semantic indexing, or assigning semantic tags to video samples, is a key component for content-based access to video documents and collections. The Semantic Indexing task has been run at TRECVid from 2010 to 2015 with the support of NIST and the Quae ...
