An operator for edge reconnection and skeletonization

Open Access

Version PDF originale



On the basis of an analogy between classical image processing problems and a simple problem of strength of materials, an operator called Δ-1 is introduced. The methodology is outlined and its advantages presented, starting by an elliptic linear partial differential equation in the form ΔA=B, where Δ represents the Laplacian. The operator's properties will not be described with mathematical formalism, but will be applied to a series of image processing problems. They will also be compared with those of other morphological operators, in order to prove their advantages.
