Next step is an estimation of parameters conditionally named as high level (HL) and low level (LL). An estimation of the levels for ramp edge is based on the assumption that the midpoint of L c separates two regions. The maximal value is calculated for half of the profile where the average amplitude grows from midpoint with index to higher values, P is the length of a profile. The maximal value corresponds to HL. The other half of the profile is processed for the estimation of a minimal value that corresponds to LL parameter. HL and LL values for roof edge are calculated by looking for global maximal and minimal values in the edge profile .

If , then pixel relates to high level plateau, otherwise . relates to low level plateau, where is:
