Flowchart for UAV image processing and analysis including illumination correction (ELM and Retinex correction), orthomosaic creation, leaves segmentation, VIs extraction, and linear regression modeling from VIs to SPAD. The workflow is o process aerial images collected under sunny, overcast and cloudy conditions with variable solar irradiance. The ELM correction was only performed in sunny and overcast conditions
