A laboratory study of the 'shoreline' detected in video imagery
… wavelengths corresponding to a standard ARGUS video imaging sensor. The dominant swash zone parameters affecting shoreline detection were found to be the presence or absence of surface foam, site-specific sediment characteristics (especially colour), and water depth. Winter versus summer solar …

The Application and Analysis of Automated Triangulation of Video Imagery by Successive Relative Orientation
… approach. Automatic orientation of strips of video frame imagery would facilitate the construction of three dimensional models with less demand on a human operator for tedious measurement. Often one has no control points, so only relative orientation is possible. The relative orientation …

Effects of Video and Cognitive Imagery on Throwing Performance of Baseball Pitchers: A Single Subject Design
… study was to examine the effects of a three week imagery and video imagery intervention program on throwing accuracy performance of individual baseball pitchers. A secondary purpose of this study was to investigate if differences in accuracy response existed in low verses high ability imagers. A …

A camcorder-based rapid mapping system
… into the potential of off-the-shelf camcorder imagery for rapid mapping. Video technology was chosen as it has the advantage of continuous image capture, enabling quick acquisition times in environments where access may be limited. Video imagery is also very low cost compared to metric …

A comparison of computer simulation techniques in depicting and communicating the visual impacts of timber harvesting in the Jefferson National Forest
… the layout to reduce the impact. New programs in video imagery offer the opportunity to design harvest layouts on a more realistic format, which may also be used as a communication tool to relay to members of the public what the proposed alteration would look like. This study compares the two …

Towards Intelligent Tumor Tracking and Setup Verification in Radiation Therapy For Lung Cancer
… direct tracking of the tumor in fluoroscopic video imagery. We tracked fixed tumor contours in fluoroscopic videos for 5 patients. The predominant tumor displacements are well tracked based on optical flow. Some tumors or nearby anatomy features exhibit severe nonrigid deformation, especially …

Unitary suprathreshold color-difference metrics of legibility for CRT raster imagery
… color contrast and legibility for digital raster video imagery. CIE colorimetric components were combined into three-dimensional color coordinate systems whose coordinates map one-to-one with the physical energy parameters of all colors. The distance between any two colors' coordinates in these …

Remote sensing techniques for geothermal investigation and monitoring in New Zealand
… research and development of a helicopter-borne video thermal infrared scanner technique and associated computer image processing methods constitutes the major portion of this study. In addition, preliminary results are presented from a related shallow ground temperature study conducted to …

Time Delay Mitigation in Aerial Telerobotic Operations Using Predictors and Predictive Displays
… setups were developed that modify the delayed video imagery that would otherwise be presented to the operator in a way that provides an almost immediate visual response to the operator's control actions. The usability of the system is determined through human performance testing with and …

The Amplified Experience
… through the use of co-operating sound and video in the form of large-scale multi-projection installations, and individual sound and video works. The Amplified Experience focuses on the characteristics, structures, phenomena and processing of sound, and on video imagery. Within the field of …

Bedrock target analysis for ROV rockdrill sampling and existing sample stratigraphic and mineralogical verification (BeTar_drill)
… that have been drilled in-situ and a series of video transects spread out across the PBC have been used to develop methods for offshore geological ‘fieldwork’, through marine bedrock mapping and sample characterisation, whilst also using footage to recreate the seafloor through …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… consolidation function of sleep. Both mental imagery and dreaming are internally generated percepts while sensory processing is more externally generated, though similar neural regions are utilized. The difference in information flow between REM sleep, mental imagery, and stimulus perception …

Design and Operational Assessment of a Mobile Robot for Undercarriage Inspection of Railcars
This research assesses the design and track operation of a track crawler robot (TCR) for practical and easy inspection of stationary railcars' undercarriages in an effort to detect any pending failures or assess any security risk of out-of-sight objects. The research leverages against a robot …

Effects of surfzone wave transformation on swash dynamics
Swash oscillations on two natural beaches were measured to show that the shape and magnitude of energy spectra can be largely dependent on processes occurring inside the surfzone. The observations took place on a steep, intermediate beach on the east coast (Tairua Beach), and a low-sloping, …

Morphodynamics of Ebb-Tidal Deltas
… at an ebb-tidal delta. A 5-year long record of video imagery was used to observe a natural mixed-energy ebb-tidal delta in the field. A semi-analytical ebb-jet model, which was coupled to an exploratory morphological model, was developed and used to explore the interactions between tidal …
