FLIP: FLuorescence Imaging Pipeline for field-based chlorophyll fluorescence images

open access: yesSoftwareX, 2021
Photosynthesis is one of the most important biological reactions on earth providing oxygen and food for humanity. As global populations rise and arable land decreases, crops need to become more efficient at photosynthetic processes, particularly ...

On the Importance of Non-Gaussianity in Chlorophyll Fluorescence Imaging

open access: yesRemote Sensing, 2023
We propose a mathematical study of the statistics of chlorophyll fluorescence indices. While most of the literature assumes Gaussian distributions for these indices, we demonstrate their fundamental non-Gaussian nature. Indeed, while the noise in the raw
