CITRUS ORCHARD MONITORING USING AERIAL CIR PHOTOGRAPHY

摘要

In this paper we report the preliminary results using aerial CIR photography for citrus pest stress monitoring in Lower Rio Grande Valley of South Texas.In order to accommodate the in-field spectral variability,unsupervised classification is applied.In addition,fully constrained linear unmixing is performed at the sub-pixel level to quantify the stress severity.This technique provides an automatic approach to quantify the stress severity without the requirement of prior information about class spectral signatures.
