Simulation of FLIR and LADAR Data Using Graphics Animation Software
Found in: Computer Graphics and Applications, Pacific Conference on
By Gavin Powell, Ralph Martin, David Marshall, Keith Markham
Issue Date:October 2000
pp. 126
This paper presents an implementation of Forward Looking Infrared (FLIR) and Laser Radar (LADAR) data simulation for use in developing a multi-sensor data-fusion automated target recognition (ATR) system. Using commercial models and software we can create ...
Ten Questions that Arose in Designing the Djinn API for Solid Modelling
Found in: Shape Modeling and Applications, International Conference on
By Adrian Bowyer, Stephen Cameron, Graham Jared, Ralph Martin, Alan Middleditch, Malcolm Sabin, John Woodwark
Issue Date:March 1997
pp. 71
Djinn is an APIfor solid modelling which is defined in the language of point-sets and is thus independent of any particular modelling data-structure (e.g. boundary representations or CSG trees). In designing this API, several significant and interesting qu...
An Evaluation Method for Multiview Surface Reconstruction Algorithms
Found in: 2012 Second International Conference on 3D Imaging, Modeling, Processing, Visualization and Transmission (3DIMPVT)
By Ran Song,Yonghuai Liu,Yitian Zhao,Ralph Martin,Paul Rosin
Issue Date:October 2012
pp. 387-394
We propose a new method, 3DGiC, for evaluating the performances of various multiview surface reconstruction methods. It does not need a complete ground truth model, providing a much wider range of applications. More importantly, most existing methods only ...
Fast and Effective Feature-Preserving Mesh Denoising
Found in: IEEE Transactions on Visualization and Computer Graphics
By Xianfang Sun, Paul Rosin, Ralph Martin, Frank Langbein
Issue Date:September 2007
pp. 925-938
We present a simple and fast mesh denoising method, which can remove noise effectively, while preserving mesh features such as sharp edges and corners. The method consists of two stages. Firstly, noisy face normals are filtered iteratively by weighted aver...
Robust Segmentation of Primitives from Range Data in the Presence of Geometric Degeneracy
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By David Marshall, Gabor Lukacs, Ralph Martin
Issue Date:March 2001
pp. 304-314
<p><b>Abstract</b>—This paper addresses a common problem in the segmentation of range images. We would like to identify and fit surfaces of known type wherever these are a good fit. This paper presents methods for the least-squares fittin...
Merging and Splitting Eigenspace Models
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Peter Hall, David Marshall, Ralph Martin
Issue Date:September 2000
pp. 1042-1049
<p><b>Abstract</b>—We present new deterministic methods that given two eigenspace models—each representing a set of <tmath>$n$</tmath>-dimensional observations—will: 1) merge the models to yield a representation of the union o...
Found in: Proceedings of the 2006 ACM symposium on Solid and physical modeling (SPM '06)
By Liangjun Zhang, Peisen Huang, Ralph Martin, Shing-Tung Yau, Song Zhang, Xianfeng Gu
Issue Date:June 2006
pp. 129-138
We introduce a novel geometric representation called the holoimage, which encodes both shading and geometry information within the same image, based on the principles of wave optics. 'Image' referes to the representation and records the amplitude of the li...
