Multispectral Photometric Stereo for Acquiring High-Fidelity Surface Normals

, 2014
Multispectral imaging and photometric stereo are common in 3D imaging but rarely have been combined. Reconstructing a 3D object's shape using photometric stereo is challenging owing to indirect illumination, specular reflection, and self-shadows ...

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

People and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

Potential of multispectral imaging technology for assessment coniferous forests bitten by a bark beetle in Central Bulgaria

MATEC Web of Conferences, 2018
Much of the coniferous forest in Bulgaria is struck by Ips typographus, Ips acuminatus and Ips sexdentatus beetles. The multispectral camera test near the town of Kalofer, Bulgaria in August 2017, showed the good capabilities of remote-piloted aircraft ...

A multispectral light field camera for 3D imaging from a single lens

, 2020
Here we present a small multispectral light field camera configuration which employs parfocal lenses and benefits from the spatial resolution of focused plenoptic cameras while exhibiting low angular bias.

Multispectral fluorescence lifetime microscopy based on computational imaging schemes

, 2023
Multispectral fluorescence lifetime microscopy (FLIM) is a valuable tool for biomedical and environmental applications. A multidimensional acquisition scheme (space, time, spectrum) provides high information content and the drawback of long acquisition ...

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Inversion of the forest dead fuel moisture content by UAV multisepectral image under the new leaves shade

Frontiers in Physics
Forest dead fuel moisture content (FDFMC) is an important factor affecting the occurrence and spread of forest fires. When the leaves have completely fallen, because of no leaves shade, the use of UAV multispectral cameras can achieve the spectral images

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...
