Paper Title:
Computer Analysis of Radar Graph Fractal Method for Wear Debris Contour
  Abstract

Radar graph fractal method is an effective description for the contour of wear debris. In this paper the principle that radar graph fractal dimension analyzed by computer was researched. In analysis, how to extract contour of wear debris from surrounding is looked as an important process, and three methods was introduced to deal with it: manual method is simple to do, but the result is not accurate for the process could be affected by human mistake; automatic method can deal with the case that multi-wear debris being in an graph, and do the statistic for the result, but it is not good for the graph that wear debris’ gray is similar to surrounding’s, the wear debris contour gotten by this method is often distortional, so the concepts that edge dot extracted ratio and the optimizing threshold method can be introduced to improve it; Semi-automatic method is easy to modify the gotten wear debris contour by change the contrast of graph and the gray of edge dot extracted artificially, improve the definition of wear debris contour. The method radar graph fractal dimension analyzed by computer is more simple and convenient than by hand, its result is also more accurate, better for the using of radar graph fractal description.
