The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Accurate prediction of grain yield (GY) remains a major challenge in plant breeding due to complex interactions between genotype, environment, and management (G × E × M) factors. Remote sensing data from unmanned aerial vehicles (UAVs) equipped with multispectral sensors have emerged as a pivotal resource for high‐throughput phenotyping.

Thermal Stress Is Associated With Fragmentation of Mediterranean Posidonia oceanica Meadows
Global Change Biology Communications, Volume 1, Issue 3, September 2026.By combining a physiological model of cumulative thermal stress with AI‐based seagrass mapping, we show that chronic sublethal warming is associated with fragmentation of Mediterranean Posidonia oceanica meadows and increased regression risk by 2100. ABSTRACT Posidonia oceanica meadows, which underpin Mediterranean coastal ecosystems, are undergoing ...

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 516-529, August 2026.ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

An experience in multispectral mosaicing
SPIE Proceedings, 2005The acquisition of large or high-resolution multispectral images may require that different parts of the scene be acquired separately and then be mosaicked to obtain the whole image. While the problem of stitching together parts of an image to form a consistent whole has been studied rather extensively for traditional images, in this case view angles ...

Large-aperture linear diffractive axicons are optical devices providing achromatic nondiffracting beams with an extended depth of focus when illuminated by white light sources. Annular apertures introduce chromatic foci separation, making chromatic imaging possible despite important radiometric losses.

Multispectral image compression
Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002Image compression has been one of the mainstream research topics in image processing. The research usually focuses on compressing images that are visible to humans. Images are usually gray-level images or RGB color images. Advances in technology enable one to make the detailed processing of spectral color features in the images.

Snapshot multispectral endomicroscopy
Optics Letters, 2020Multispectral endomicroscopy provides tissue functional information in addition to structural information for accurate disease diagnosis. In this Letter, we propose a snapshot multispectral endomicroscope that employs a fiber bundle to deliver an in-body tissue spatial–spectral datastream to an external compressive spectral imager. Equipped with an end-

The shortcomings of the conventional three-channel imaging are rooted in metamerism problems. To avoid these problems multispectral imaging is introduced as an complementary approach. This imaging technology uses the complete spectral information of the original image, and, hence, avoids the problems due to metamerism.
