%description
Tools to estimate the Canopy Openness Index (COI) from hemispherical
(fisheye) canopy photographs. The package imports canopy images, crops
them to the circular area delimited by the fisheye lens, binarizes them to
separate sky from vegetation pixels, and computes the index as the
proportion of sky pixels in the cropped image. Canopy openness is a
measure related to canopy closure, canopy cover and understorey
illumination, as discussed in Jennings, Brown and Sheil (1999) "Assessing
forest canopies and understorey illumination: canopy closure, canopy cover
and other measures" <doi:10.1093/forestry/72.1.59>. Example canopy images
are included so users can test the workflow.
