The Application and Research of Filtering Algorithm of the Acceleration Signal of Human Movement Based on Mathematical Morphology-Median Filtering Algorithm

Abstract

In order to have better research and application of acceleration of human movement, reduce the complexity of the denoising algorithm, so as to achieve the good signal more quickly in the microprocessor chip, this paper presents a method based on mathematical morphology and median filtering algorithm according to the principle of mathematical morphology. First of all, it filters the signal baseline drift with morphological filter, then removing the impulse noise with median filter, finally smoothing the waveform by average filter. Processing the data on the MSP430 microcomputer verifies the reliability of the proposed algorithm.
