areal feature main skeleton extraction al gorithm

  • a new al gorithm based  the delaunay trian gulated network and  its  improved al gorithm isproposed  to  implement  area  feature  automatic skeleton  line  extraction.a delaunay trian gulated network al gorithm was improved  to be better  applied  to more complex  area  feature  of  the  trian gular  network establishmentthe  existence of  a lar ge number of  smaller trian gles  in  the  facet  element  trian gulation  boundary re gion was carried outan effective  processing al gorithm was proposed  to  improve  theskeleton extraction efficienc ytrian gle was considered  the  smallest unit as  a node of  the  tree  and an ef fective  binar y tree  structure  based on trian gulation was presentedtrifurcate  chain-table  stora ge structure was used  to make the binar y tree  traversal  more strai ghtforward.the  experimental  resultsshowed  that  the proposed concepts  and al gorithms  for main skeleton extraction to be more effective.
