111. Reconstructing Images of Bar Codes for Construction Site Object Recognition
Topic: Modeling
Published: 9/1/2002
Authors: David E. Gilsinn, Geraldine S Cheok, Dianne M O'Leary
Abstract: This paper discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADARoptics. The first part of this paper describes the experimental data collection of several bar code images along w ...

112. Registration of Six Degrees of Freedom Data with Proper Handling of Positional and Rotational Noise
Series: Journal of Research (NIST JRES)
Report Number: 118.013
Topic: Modeling
Published: 6/6/2013
Author: Marek Franaszek
Abstract: When two six degrees of freedom (6DOF) data are registered (e.g., robot-world/hand-eye calibration), a transformation is sought which minimizes the misalignment between the two datasets. Often, the measure of misalignment is the sum of the posit ...

114. SHREC‰12 Track: Generic 3D Shape Retrieval
Topic: Modeling
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 ...

Topic: Modeling
Published: 5/13/2012
Authors: Bo Li, Afzal A Godil
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 implemented by different parti ...

116. SHREC‰13 Track: Large Scale Sketch-Based 3D Shape Retrieval
Topic: Modeling
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 ...

117. Salient Local 3D Features for 3D Shape Retrieval
Topic: Modeling
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 ...

118. Sensitivities and Variances for Fitted Parameters of Spheres
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7616
Topic: Modeling
Published: 7/1/2009
Authors: Christoph Johann Witzgall, Marek Franaszek
Abstract: Experimental data have been gathered by applying 3D imaging systems, such as LIDAR/LADAR instruments, to spherical objects. This report provides a compilation of the statistical and analytical procedures to be used for an evaluation, to be reported ...

119. Separation of variables in an asymmetric cyclidic coordinate system
Topic: Modeling
Published: 6/27/2013
Authors: Howard S Cohl, Hans Volkmer
Abstract: A global analysis is presented of solutions for Laplace's equation on three-dimensional Euclidean space in one of the most general orthogonal asymmetric confocal cyclidic coordinate system which admits solutions through separation of variables. ...

120. Shape Calculus for Shape Energies in Image Processing
Topic: Modeling
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 ...
