A Modified Contour Tracing Algorithm of Rectangular Grid
Xu Dong Wu · Journal of Henan Normal University · 2008
This paper has it is introduced that the contour tracing algorithm of rectangular grid with synchronization of point's generation and contour tracing.It improves the traditional rectangular grid contour track algorithm by the function of contour tracing back.And contour point generating and contour tracing can work at the same time.With the function,either a non-closed contour or a closed contour can be quickly traced out from every point on it.
