31. SHREC‰12 Track: Generic 3D Shape Retrieval
Topic: Imaging
Published: 5/13/2012
Authors: Bo Li, Afzal A Godil
Abstract: Generic 3D shape retrieval is a fundamental research area in the field of content-based 3D model retrieval. The aim of this track is to measure and compare the performance of generic 3D shape retrieval methods implemented by different participant ...

34. 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 ...

35. 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 ...

36. 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 ...

37. 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 ...

38. 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 ...

39. 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 ...

40. Terabyte Size Image Computations on Hadoop Cluster Platforms
Topic: Imaging
Published: 10/7/2013
Authors: Peter Bajcsy, Antoine Vandecreme, Julien Marc 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 ...
