Abstract:The key problem for applying the technique of computer image treatment to analysis of ferrography wear particle is how to extract the morphology characteristics of wear particle. Through the introduction of the newest development of morphology characteristics extraction of wear particle, the applications of fractal dimension and Spike parameter in analysis of wear particle have been discussed emphatically, and the applying ranges of several analysis methods were pointed out. All those are available for further research of identification of ferrography wear particle in theory and practice.
Key words: image treatment ferrography wear particle analysis
