Paper Title:
Study on Method to Extract Feature Parameter of Wear Particle Group in Ferrographic Image for the Diesel Engine Lubricants
  Abstract

According to the consistency between multi-scale decompositions and self-similarity in both wavelet transform and fractal theory, a new method has been developed to extract the feature parameter of wear particle group on the ferrographic image for diesel engine lubricants. The algorithm of minutiae extraction have been carried out by wavelet transform approach and the fractal dimension, and then the feature parameter can be obtained for the wear particle group on the ferrographic image. The fractal dimension D reflects the ferrographic image character in the scale and the amount of wear particle group, which can be used as a comprehensive feature parameter. The metal-ceramic nano-lubricant, which has been applied in the wear test of cylinder and piston-ring material from MAN B&WS50MC marine diesel engine, represent that the wear is speedup suitably, and then the fractal dimension D has consistency with the results of ferrographic analysis.
