from that also Fuzzy Membership.

For line objects (
Fuzzy Membership is calculated for depth and
height as well, besides that, also width of an object is considered. For Euclidean
distance 10 m, conditions for fuzzification are:

depth were used in the calculation. Fuzzification was calculated for Euclidean
distance 20 m.
