Hyperspectral reflectance as a tool to measure biochemical and physiological traits in wheat.
Improving photosynthesis to raise wheat yield potential has emerged as a major target for wheat physiologists. Photosynthesis-related traits, such as nitrogen per unit leaf area (Narea) and leaf dry mass per area (LMA), require laborious, destructive, laboratory-based methods, while physiological traits underpinning photosynthetic capacity, such as maximum Rubisco activity normalized to 25 °C (...
متن کاملChromaticity as a signal of ripeness in fruits taken by primates.
We have measured the reflectance spectra of many samples of fruit eaten by chimpanzees and three frugivorous monkey species. If the fruit are plotted in a colour space appropriate for catarrhine primates, several distinct ripening patterns are evident. The degree of ripeness of many species would be discernible by dichromatic primates, but for most fruit a trichromatic consumer would be at an a...
متن کاملQuantitative Hyperspectral Reflectance Imaging
Hyperspectral imaging is a non-destructive optical analysis technique that can for instance be used to obtain information from cultural heritage objects unavailable with conventional colour or multi-spectral photography. This technique can be used to distinguish and recognize materials, to enhance the visibility of faint or obscured features, to detect signs of degradation and study the effect ...
متن کاملHyperspectral Image Analysis for Measuring Ripeness of Tomatoes
The latest developments in optics and sensors allow imaging spectrometry: the creation of hyperspectral images, i.e. images with wavelength-specific measurements over a large part of the spectrum. In this study, hyperspectral images of several stages of ripeness of tomatoes were recorded and analyzed. The electromagnetic spectrum between 450 and 850 nm was recorded in 80 bands (every 5 nm). Res...
