Abstract:

In this paper, the principle of mathematical morphology is briefly introduced. A new signal processing method based on mathematical filtering is prese nted. In order to remove noises and the DC offset, a filter with structural elements based on morphological open and closed operators is designed. With   the structural elements, signals can be detected and smoothed. Simulation results and practical applications show that the method is   s proved that the method is also effective in dealing with the pulsed noises in vibration data.
