Enhanced Discrimination of Thawed and Nonfrozen Chicken Thighs Using Convex Hull Peeling in Visible Spectral Imaging

open access: yesJournal of Chemometrics, Volume 39, Issue 8, August 2025.
ABSTRACT Hyperspectral imaging (HSI) combines spectral and spatial data, producing complex 3D datasets that require efficient data reduction methods for improved computational efficiency and prediction accuracy. This study introduces convex hull peeling to enhance the discrimination of thawed and nonfrozen chicken thighs.

Estimating Sea Ice Algal Biomass in Svalbard Fjords Using Underwater Hyperspectral Imaging: Integrating Laboratory and Field Calibration Approaches

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract Sea‐ice algae are an integral part of the polar marine ecosystems, but they remain under‐sampled due to the limitations of invasive sampling techniques, the large spatial heterogeneity of their biomass and logistical challenges conducting research in remote regions.

Prediction of nutritive values, morphology and agronomic characteristics in forage maize using two applications of NIRS spectrometry

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
This study evaluates nutritive, morphological and agronomic characteristics of forage maize predicted by using a high-quality near-infrared (NIR) spectrometer and an NIR hyperspectral-imaging technique using partial least squares (PLS) regression models.

High‐Speed Hyperspectral Imaging for Near Infrared Fluorescence and Environmental Monitoring

open access: yesAdvanced Science, Volume 12, Issue 16, April 24, 2025.
This study introduces a fast hyperspectral imaging method in the near‐infrared range (HyperNIR). Combining tunable polarization optics with a phasor‐based approach, HyperNIR captures detailed spectral information with just three images. The applicability is showcased by distinguishing NIR fluorophores that are separated by 5 nm.

Crater Projection in Linear Pushbroom Camera Images

open access: yesThe Journal of the Astronautical Sciences
Abstract Scientific imaging of the Moon, Mars, and other celestial bodies is often accomplished with pushbroom cameras. Craters with elliptical rims are common objects of interest within the images produced by such sensors. This work provides a framework to analyze the appearance of crater rims in pushbroom images.
