Investigation on a modular high speed multispectral camera [PDF]
, 2012 Multispectral imaging grows in importance in an increasing field of image processing applications. The reason for it is that they provide substantially more spectral information than for example RGB (red-green-blue) colour cameras.

Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Wildlife Letters, EarlyView.This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

The Use of Unmanned Aerial Systems to Map Intertidal Sediment
Remote Sensing, 2018 This paper describes a new methodology to map intertidal sediment using a commercially available unmanned aerial system (UAS). A fixed-wing UAS was flown with both thermal and multispectral cameras over three study sites comprising of sandy and muddy ...

Multispectral video acquisition using spectral sweep camera
Optics Express, 2019 This paper proposes a novel multispectral video acquisition method for dynamic scenes by using the Spectral-Sweep camera. To fully utilize the redundancies of multispectral videos in the spatial, temporal and spectral dimensions, we propose a Complex Optical Flow (COF) method that could extract the spatial and spectral signal variations between ...

X-Ray Spectrometry, EarlyView.ABSTRACT In this study, a non‐invasive, multi‐analytical approach combining hypercolorimetric multispectral imaging (HMI), stereomicroscopy, X‐ray fluorescence (XRF) spectroscopy, principal component analysis (PCA) and X‐ray radiography (RX) is used to investigate three reused musical parchment fragments dating from the late 14th or early 15th century ...

Journal of Animal Ecology, EarlyView.Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

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 ...
