vm_p_sphere(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

ratio between radius of maximum inscribed circle and minimum circumscribing circle
