binarize_fisheye Compute the threshold of a single-channel fisheye image, and return a binary fisheye image of canopy (0) and gap (1) pixels
camera_fisheye Provide circular mask parameters from known camera+fisheye lens models
canopy_fisheye Calculate canopy attributes from angular gap fraction data derived from fisheye images
gapfrac_fisheye Derive angular gap fraction from a classified fisheye image
import_fisheye Import a fisheye image as a single channel raster, and apply a circular mask
list.cameras Import a fisheye image as a single channel raster, and apply a circular mask
list.lenses Derive angular gap fraction from a classified fisheye image
zonal_mask Divide a raster image into four stacks which are used as masks.
