Optimize distance to black

Description

Optimize distance to black

Usage

optim_dist_to_black(r, z, a, m, bin, g)

Arguments

r	SpatRaster. A normalized greyscale image. Typically, the blue channel extracted from a canopy photograph. Please see read_caim() and normalize_minmax().
z	SpatRaster built with zenith_image().
a	SpatRaster built with azimuth_image().
m	SpatRaster. A mask, check select_sky_vault_region().
bin	SpatRaster. This should be a preliminary binarization of r useful for masking pixels that are very likely pure sky pixels.
g	SpatRaster built with sky_grid_segmentation() or chessboard().

Value

Numeric vector of length one.
