Sea-thru: A method for removing water from underwater images
Robust recovery of lost colors in underwater images remains a challenging problem. We
recently showed that this was partly due to the prevalent use of an atmospheric image …

Principles and practice of acquiring drone-based image data in marine environments
With almost limitless applications across marine and freshwater environments, the number
of people using, and wanting to use, remotely piloted aircraft systems (or drones) is …

3D photogrammetry quantifies growth and external erosion of individual coral colonies and skeletons
Growth and contraction of ecosystem engineers, such as trees, influence ecosystem
structure and function. On coral reefs, methods to measure small changes in the structure of …

Cost and time-effective method for multi-scale measures of rugosity, fractal dimension, and vector dispersion from coral reef 3D models
We present a method to construct and analyse 3D models of underwater scenes using a
single cost-effective camera on a standard laptop with (a) free or low-cost software,(b) no …

End of the chain? Rugosity and fine-scale bathymetry from existing underwater digital imagery using structure-from-motion (SfM) technology
CD Storlazzi, P Dartnell, GA Hatcher, AE Gibbs - Coral Reefs, 2016 - Springer
The rugosity or complexity of the seafloor has been shown to be an important ecological
parameter for fish, algae, and corals. Historically, rugosity has been measured either using …

A quick, easy and non‐invasive method to quantify coral growth rates using photogrammetry and 3D model comparisons
Coral growth rates vary significantly with environmental conditions and are thus important
indicators of coral health and reef carbonate production. Despite the importance of this …

No apparent trade-offs associated with heat tolerance in a reef-building coral
As marine species adapt to climate change, their heat tolerance will likely be under strong
selection. Yet trade-offs between heat tolerance and other life history traits could …

Habitat structural complexity metrics improve predictions of fish abundance and distribution
Habitat structural complexity influences biotic diversity and abundance, but its influence on
marine ecosystems has not been widely addressed. Recent advances in computer vision …
