Marine ship instance segmentation by deep neural networks using a global and local attention (GALA) mechanism.

PLoS ONE, 2023
Marine ships are the transport vehicle in the ocean and instance segmentation of marine ships is an accurate and efficient analysis approach to achieve a quantitative understanding of marine ships, for example, their relative locations to other ships or ...

Underwater hyperspectral imaging: a new tool for marine archaeology [PDF]

Applied Optics, 2018
By applying an underwater hyperspectral imager (UHI) to a selection of archaeological artifacts, we have found spectral signatures that are representative of materials likely to be present at wreck sites. By successfully using the signatures to classify a subset of said artifacts placed on the seabed at 61 m depth, we demonstrate that it is possible to

A Highly Selective Turn-on Fluorescent Probe for the Detection of Aluminum and Its Application to Bio-Imaging

Sensors, 2019
Aluminum is the most abundant metallic element in the Earth’s crust and acts as a non-essential element for biological species. The accumulation of excessive amounts of aluminum can be harmful to biological species.

Evaluation of photon-counting micro-CT scanning for imaging marine organisms

Frontiers in Marine Science
IntroductionAnatomical information is crucial in marine biology research. Traditionally, destructive techniques, such as slice imaging of the sample, are used to image the inside of the sample, which are unsuitable for valuable or rare specimens.
