Spatiotemporal mapping the usable space of free‐roaming equids across the western United States

Wildlife Society Bulletin, EarlyView.
Identification of the inter‐decadal (2010‐2011) enhancement‐degradation gradients in the usable space for wild equid Herd Management Areas in the Great Basin, USA. Abstract Management of feral equids in the American West is hindered by the lack of a formal habitat map and monitoring system.

Comparing a single target image with a reference three‐dimensional (3D) virtual avatar of a real person

Journal of Forensic Sciences, EarlyView.
Abstract The demand for analyzing images from sources such as closed‐circuit television cameras has increased significantly. Conventional analyses, including gait and soft biometrics, typically require the comparison of two video footage clips, as these methods are predicated on video‐to‐video comparisons.

3D scene reconstruction from body‐worn camera video using 3DF Zephyr

Journal of Forensic Sciences, EarlyView.
Abstract Body‐worn cameras document crime scenes during initial law enforcement response, yet their potential for forensic reconstruction has not been empirically validated. Despite expanding global adoption, recorded video primarily serves qualitative documentation rather than quantitative measurement applications.

Using 3DF Zephyr to determine body‐worn camera position

Journal of Forensic Sciences, EarlyView.
Abstract Photogrammetry has been used consistently in forensic settings to document crime scenes three‐dimensionally. Traditionally, a large number of still photos are taken, and information from those photos is used to create a three‐dimensional (3D) model.

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

Integrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...

Experimental Investigation of Photogrammetric Surface Analysis of Heat Shield Materials during Plasma Wind Tunnel Testing [PDF]

, 2013
The paper presents first results of an experimental analysis of surface recession using advanced photogrammetric tools. Based on image pairs acquired with two DSLR cameras, classical photogrammetry has been tried, but pixelwise image analysis with ...

Behavioral, Ecological, and Morphological Data Suggest a Close Relationship Between the Ant Colobopsis truncata and the Gall Wasp Aphelonyx cerricola

Integrative Zoology, EarlyView.
Aphelonyx cerricola and the different stages that make this gall colonizable by ants. ABSTRACT Wasps of the family Cynipidae are known to induce galls of a species‐specific morphology, which during senescence provide a refuge for secondary insect fauna, especially ants.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

Integrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

As above, so below: A perspective into the application of land‐forest monitoring methods for the assessment of marine animal forests

Methods in Ecology and Evolution, EarlyView.
Abstract Marine animal forests (MAFs) are benthic ecosystems dominated by vertically structuring filter‐ and suspension‐feeders. As terrestrial forests, they are considered biodiversity hotspots, forming canopies, serving as a refuge, nursery, reproduction and feeding shelters for many species.

A Fully Convolutional Network for Semantic Labeling of 3D Point Clouds

, 2017
When classifying point clouds, a large amount of time is devoted to the process of engineering a reliable set of features which are then passed to a classifier of choice.
