Estimation of vegetation traits with kernel NDVI
ISPRS Journal of Photogrammetry and Remote Sensing, 2023 Vegetation indices computed from spectral signatures are vastly used for monitoring the terrestrial biosphere. Indices are convenient proxies for canopy structure, and leaf pigment content, and consequently to estimate the photosynthetic activity of vegetation.

NDVI Computation from Hyperspectral Images
2023 13th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2023 Agriculture has witnessed a series technological transformations over time. In recent years, multispectral and hyperspectral satellites have become powerful tools in precision and efficient agricultural practices. Given the richness of information they provide and the fact that multi- and hyperspectral data are not easy to interpret, a consistent ...
