The production of cobalt-60 is critical to healthcare and, with demand soaring, the challenge is to expand supply, writes Martin Comben from the International Irradiation Association.
MODEL BASED VIEWPOINT PLANNING FOR TERRESTRIAL LASER SCANNING FROM AN ECONOMIC PERSPECTIVE
Terrestrial laser scanning viewpoint planning registration ray casting economic considerations
2016/11/11
Despite the enormous popularity of terrestrial laser scanners in the field of Geodesy, economic aspects in the context of data acquisition are mostly considered intuitively. In contrast to established...
Photographing Long Scenes with Multi-Viewpoint Panoramas
Multi-Viewpoint Panoramas Photographing Long
2016/5/24
We present a system for producing multi-viewpoint panoramas of
long, roughly planar scenes, such as the facades of buildings along a
city street, from a relatively sparse set of photographs captured...
Learning viewpoint invariant perceptual representations from cluttered images
Computational models of vision Neural Nets invariance object recognition
2015/7/31
In order to perform object recognition, it is necessary to form perceptual representations that are sufficiently specific to distinguish between objects, but that are also sufficiently flexible to gen...
Viewpoint: Assessing the reality—Transport and land use planning to achieve sustainability
Transport Land Use Development Megacities Urban planning
2013/11/21
This paper takes a historical perspective on how cities have become less sustainable in terms of transport, but it will argue that many positive changes have taken place even before the current concer...

SPATIAL COMPARISON BETWEEN DENSELY BUILT-UP DISTRICTS FROM THE VIEWPOINT OF VULNERABILITY TO ROAD BLOCKADES WITH RESPECT TO EVACUATION BEHAVIOR
GIS Urban Model Planning City Simulation Hazards
2014/4/25
In a densely built-up area, it is conceivable that road blockades will occur widely because of building collapse caused by earthquakes. The road blockades on evacuation routes have a bad influence on ...
Transferring Boosted Detectors Towards Viewpoint and Scene Adaptiveness
Boosting covariate shift detector adaptiveness object detection transfer learning
2013/7/24
In object detection, disparities in distributions between the training samples and the test ones are often inevitable,resulting in degraded performance for application scenarios. Inthis paper, we focu...
The Viewpoint Paradigm: a semiotic based approach for the intelligibility of a cooperative designing process
Viewpoint Paradigm semiotic cooperative designing process
2009/12/7
The concept of viewpoint is studied in the field of the modelling and the knowledge management concerned in the upstream phases of a designing process. The concept is approached by semiotics, i.e. in ...
Design of a Feature-based Multi-viewpoint Design Automation System
Computer-aided design Feature-based design Viewpoint dependency
2009/8/19
Viewpoint-dependent feature-based modelling in computer-aided design is developed for the purposes of supporting engineering design representation and automation. The approach of this paper uses a com...
How to overcome the confusion around the terms, “turbidity current” and “turbidite”—some discussion on the definition of these terms, especially from a historical viewpoint—
sediment gravity flow turbidity current turbidite density current
2009/4/8
The term “turbidity current” was firstly proposed for the unknown subaqueous density current, weighted with sediments in water, which is proposed to explain the origin of submarine canyons (Daly, 19...
A Virtual View Generation Method for Free-Viewpoint Video System
View Generation Method Free-Viewpoint Video System
2010/12/16
Generating virtual views is one of the crucial problems for a free-viewpoint video system. In this paper, we solve the problem by using a method based on the technique of view
morphing, and construct...
Viewpoint invariance is a grand challenge for sign language recognition. In this paper, we propose a novel viewpoint invariant method for sign language recognition. The recognition task is converted t...
Free viewpoint switching in multi-view video streaming using Wyner-Ziv video coding
multi-view video streaming Wyner-Ziv video coding
2010/12/16
The free viewpoint switching is one of the most important features of multi-view video streaming. The key problem lies in how to achieve the best performance when the camera processing capability and ...
A Verification Method for Viewpoint Invariant Sign Language Recognition
Viewpoint Invariant Sign Language Recognition
2010/12/16
Viewpoint variance is one of the inevitable problems in vision based sign language recognition.However, most researchers avoid this problem by assuming a special view, especially the front view. In th...
