Subboundary statistics evaluate the contiguity of difference boundaries. A subboundary is a set of connected Boundary Elements (BEs).
NS
number of subboundaries found
N1
number of singleton BEs
Lmax
maximum subboundary length (number of linked BEs)
Lmean
mean subboundary length
Dmax
maximum subboundary diameter
Dmean
mean subboundary diameter
D/L
mean diameter-to-length ratio (indicates branchiness)
Subboundary diameter is the shortest path length between each pair of BEs in a subboundary.
