Object representation and comparison inferred from its medial axis

摘要: The skeleton and its associated medial axis give a very compact representation of objects, even in the case complex shapes topologies. They are powerful shape descriptors, bridging gap between low-level high-level object representations. Surprisingly, skeletons have been used relatively small number applications. This work deals with question using potential strength axis. From axis, we build adequate attributed relational graphs to organize structured way informations about topology contained then permits us compare meaningful various objects graph matching algorithm. Synthetic results presented.
