Influence of noise spot and valid membrane region on the EDT of membrane surface. This figure includes steps in region filter. a Largest membrane surface ϕmax; b Add noise spot ϕi to ϕmax; c EDT of noise and ϕmax; d Add valid membrane ϕi to ϕmax; e EDT of membrane and ϕmax. Path (a)-(b)-(c) shows when a noise spot is added into the largest membrane surface, the influenced region R (transparent white mask in (c) and (e)) in the EDT tends to be round. Conversely, Path (a)-(d)-(e) indicates if a valid membrane region is added into the membrane surface, the influenced region has notable polarization. Note that noise spot (yellow in (b)) and valid membrane region (blue in (d)) all exist in binary filtered membrane Ibn, but shown here separately for better demonstration
