Capturing complexity: field-testing the use of ‘structure from motion’ derived virtual models to replicate standard measures of reef physical structure [PDF]
PeerJ, 2019 Reef structural complexity provides important refuge habitat for a range of marine organisms, and is a useful indicator of the health and resilience of reefs as a whole.

Mapping Glacier Ablation With a UAV in the North Cascades: A Structure-from-Motion Approach
Frontiers in Remote Sensing, 2022 The glaciers of the North Cascades have experienced mass loss and terminus retreat due to climate change. The meltwater from these glaciers provides a flux of cold glacier meltwater into the river systems, which supports salmon spawning during the late ...

Identifying mechanisms of shore platform erosion using Structure‐from‐Motion (SfM) photogrammetry [PDF]
Earth Surface Processes and Landforms, 2019 AbstractShore platforms control wave energy transformation which, in turn, controls energy delivery to the cliff toe and nearshore sediment transport. Insight into shore platform erosion rates has conventionally been constrained at millimetre‐scales using micro‐erosion metres, and at metre‐scales using cartographic data.

Perceptual Biases in the Interpretation of Non-Rigid Shape Transformations from Motion
VisionMost existing research on the perception of 3D shape from motion has focused on rigidly moving objects. However, many natural objects deform non-rigidly, leading to image motion with no rigid interpretation.

Journal of Forest Science, 2018 The wood yield of hedge banks is very heterogeneous and hard to estimate in advance. The aim of the present study was to estimate the dry biomass of hedge banks shortly before harvesting using two different non-destructive approaches: (i) allometric ...

Rough or Noisy? Metrics for Noise Estimation in SfM Reconstructions
Sensors, 2020 Structure from Motion (SfM) can produce highly detailed 3D reconstructions, but distinguishing real surface roughness from reconstruction noise and geometric inaccuracies has always been a difficult problem to solve.

Archival photogrammetric analysis of river–floodplain systems using Structure from Motion (SfM) methods [PDF]
Earth Surface Processes and Landforms, 2016 AbstractIn this study we evaluate the extent to which accurate topographic data can be obtained by applying Structure from Motion (SfM) photogrammetric methods to archival imagery. While SfM has proven valuable in photogrammetric applications using specially acquired imagery (e.g. from unmanned aerial vehicles), it also has the potential to improve the

Advanced Science, EarlyView.A conductive ZrB2 ceramic composite strategy was developed for Mg3(Sb, Bi)2 thermoelectrics to regulate carrier transport and phonon scattering through heterointerface engineering. The 1.0 wt.% ZrB2 composite achieved enhanced room‐temperature performance, with a power factor of 28.51 µW cm−1 K−2 and a peak ZT of 1.22 at 573 K.
