This function allows you to calculate the ratio between the patch area and perimeter. The ratio describes the patch complexity in a straightforward way.

vm_c_perarea_mn(landscape, class_col)

Arguments

landscape: the input landscape image,
class_col: the name of the class 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.
