Analysis of skeleton junctions in 3×3 windows
E. Roy Davies, D. Celano · Electronics Letters · 1993
The Letter studies the formation and analysis of skeletons in binary images. Particular emphasis is placed on the concept of crossing number which is found to be subtly different when testing a point known to be on a skeleton and testing whether a point is on a skeleton: these ideas are applied to the elimination of noise spurs from skeletons.
