crop_caim

Extracts a rectangular region of interest (ROI) from a canopy image. This
function complements <code>read_caim()</code> and <code>read_caim_raw()</code>.

Tools for preprocessing and processing canopy photographs with
support for raw data reading. Provides methods to address variability in
sky brightness and to mitigate errors from image acquisition in
non-diffuse light. Works with all types of fish-eye lenses, and some
methods also apply to conventional lenses.
