hemispheR: Processing Hemispherical Canopy Images
Import a fisheye image as a single channel raster, and apply a circula...
Divide a raster image into four stacks which are used as masks.
Import and classify canopy fish-eye images, estimate angular gap fraction and derive canopy attributes like leaf area index and openness. Additional information is provided in the study by Chianucci F., Macek M. (2023) <doi:10.1016/j.agrformet.2023.109470>.
