I took a bunch of hemispherical vegetation images with a fisheye lense in the field. Now I am looking for a software that can (semi-)automatically translate these images in LAI values. So far I struggled with CanEye but didn't get results. Anybody knows a good freeware solution?
I was just looking for the same and found CAN-EYE by INRA. Not only are they really the scientific leaders on this research, but they have made it available for free to everyone. CAN-EYE is an imaging software (Windows) used to extract the following canopy structure characteristics from true-color images (either acquired with a fish-eye or with a classic objective)
LAI : Leaf Area Index ALA : Average Leaf inclination Angle FAPAR : Fraction of Absorbed Photosynthetically Active Radiation FCOVER : Vegetation cover fraction Bidirectional gap fraction
CAN-EYE is a free software developed since 2003 at EMMAH (Environnement Mediterranéen et Modélisation des Agro-Hydrosystèmes) by INRA (french National Institute of Agronomical research).
