This package provides two functions useful for processing hemispherical canopy cover photos. darkpix
, which processes a single photographic image file, extracts the central circle representing the hemispherical horizon, and calculates the percentage of dark (cover) pixels, and darkpix.dir
, which applies the darkpix
function to an entire directory of images, and returns a data frame.
