Development of High Speed High Dynamic Range Videography
High speed video has been a significant tool for unraveling the quantitative and qualitative assessment of phenomena that is too fast to readily observe. It was first used in 1852 by William Henry Fox Talbot to settle a dispute with reference to the synchronous position of a horse's hooves while …

Viewpoint-Aware Task Planning and Model Predictive Control for Applications in Videography and Multi-Target Tracking
We seek to combine high level planning with low level reactive control to solve a variety of viewpoint-constrained target following tasks. In the scenarios we consider, a team of tracking agents is desired to gain some sort of visual information about one or more target agents. A high level …

Human oocytes and embryos viewed by time-lapse videography, and the development of an embryo deselection model
Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse …

Detecting the Presence of Disease by Unifying Two Methods of Remote Sensing.
… by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change …

Distribution, Productivity, and Habitat Use by Interior Least Terns and Piping Plovers on the Niobrara River in Northern Nebraska, 1996-1997
… and habitat use were also evaluated. Aerial videography was flown for the Niobrara River in early June of 1996 and 1997. Sandbar characteristics including total area and areas of high, low, wet sand, and heavy vegetation were obtained from the videography. Least terns and piping plovers were …

Studying wildfire spread using stationary burners
… flame geometry was determined using high-speed videography. Important two-dimensional flame geometry parameters such as centerline flame length and flame tilt angle were measured from these images. Flame intermittency and pulsation close to the surface was measured using high-speed videography …

Nesting Biology of Osmia cornifrons: Implications for Population Management
… resulting from abiotic factors by utilizing videography techniques. Osmia cornifrons daily activity was measured as the number of trips initiated from the nest every hour. The effects of time of day, temperature, and precipitation on O. cornifrons activity were determined using non-linear …

Land Cover of Virginia From Landsat Thematic Mapper Imagery
… other maps were used as training data. Aerial videography transects were flown to acquire reference data. Due to the spatial inaccuracies inherent in the videography reference data, only homogeneous land cover areas were used in the accuracy assessment. The results of the overall accuracy for …

Development of a test suite for single object tracking algorithms in video
… startup accelerator, intends to provide drone videography to paying customers in ski resorts: a customer should be able to go about their activity as usual while a drone films them. Visual object tracking, enabling the drone to track the customer throughout the activity, is a primary obstacle …

The Ballistic Response of Particle-Filled Elastomeric Systems
… velocities were measured using high-speed videography techniques. Three projectile nose geometries were considered (i.e., flat-nosed, chisel-nosed, and hemispherical) in order to note differences in the ballistic response of composites.

A conformable ultrasound patch for cavitation enhanced transdermal cosmeceutical delivery
… acoustic spectrum analysis and high-speed videography are used to characterize transducer deflection, acoustic pressure fields and resulting cavitation bubble dynamics in the coupling medium. The final system demonstrates a 26.2-fold enhancement in niacinamide transport in a porcine model …

Feeding kinematics of the grotto salamander, Eurycea spelaea
… to determine stereotypy using high-speed videography and kinematic analysis, and then was compared across several taxa. The salamander feeds using the conserved aquatic feeding pattern with three observable stages: expansion, compression, and recovery. Like other inertial suction feeders, …

Implementation of a communication skills module at the University of Washington School of Dentistry: pilot study
… a communication module with role-playing and videography is an effective method for teaching communication skills and improving students’ perception of their own communication skills. Rubric scores as well as peer assessment scores were correlated, suggesting their use for proving competency …

The contribution of the pectoral fins, body, and the ribbon fin to turning maneuvers of a gymnotiform swimmer
… and during steady swimming using high speed videography. 3D kinematic analysis of the body, pectoral fins, and ribbon fin revealed that pitch angle, ribbon fin amplitude, and asynchronous movements of the pectoral fins dominated steady swimming while ribbon fin wavelength, frequency, wave …

Characterization and Control of an Electrospinning Process
… of polymer solutions. Combinations of videography, stereography, and methods for illumination of the multiple coils of an electrospinning jet path, that depend on bright glints of reflected light from the jet, recorded quantitative information about the location and vector velocity of …

The Effects of Amphetamine Exposure on Neurodevelopment and Behavior in Early Life Stages of Danio Rerio
… 48 hours of development and used high-speed videography to identify escape behavior deficits at two time points. All doses of amphetamine exposed embryos took significantly longer to complete escape behaviors compared to controls at both time points and also displayed an increase in spastic …

Evolutionary co-option of trap-jaw ant mandible strikes: defensive interactions with antlions
… Using behavioral observations, high-speed videography, and traditional bioassays, I describe how trap-jaw ants can use their mandible strikes to escape from antlion pits. Interestingly, while both species use the mandible snap for predation, only O. brunneus use the mandible snap to escape …
