• Topological Considerations on Gray Level Skeletonization 

      Madrid, Joaquin; Mersereau, Russell M.; Ezquerra, Norberto F. (Georgia Institute of Technology, 1993)
      Analyzing the topological properties of algebraic opening and closing, we characterized the skeletonization of gray level signals as a homotopic transformation; i.e. a continuous deformation of the signal into a simple ...
