Calculate perimeter of the convex hull of the polygon

get_hull_perim(landscape, class_col = NULL, patch_col = NULL)

Arguments

landscape

the input landscape image,

class_col

the name of the class column of the input landscape

patch_col

the name of the id column of the input landscape

Value

the function returns tibble with the calculated values in column "value", this function returns also some important information such as level, class, patch id and metric name.

Details
