Arguments

`las`	'LAS' object from 'lidR' package representing individually segmented tree
`crown_base_height`	numeric - height of crown base for segmentation. 'NULL', it is estimated with [get_crown_base()] using default parameters.

Value

The input 'LAS' object with a new attribute 'Crown' (1 = crown, 0 = non-crown).
