Abstract
Ferography analytical method is required to detect the wear particles in the lubricating oil automatically, because in the customary way it is involved a sacrifice of a great deal of time. We propose a new method to detect the wear particles in the lubricating oil to diagnose the bearing by means of local spatial frequency analysis using Wavelet Transform. Gabor function and cylindrical Gabor function are used as the mother function of Wavelet Transform in this paper. Gabor function is effective to detect the particles which distribute along the line of magnetic force on the Ferogram slide. Cylindrical Gabor function can detect the circular particles. And to discriminate the particles, we apply the Fuzzy Systems Theory to the image transformed by two Gabor function and show the effectiveness of this method.
