Different from traditional spatial or frequency domain image denoising and image enhancement method, discussed the characteristics of rotor flowmeter image, then tried to use the wavelet denoising and wavelet enhancement for its pretreatment, and further realized the rotor flowmeter reading. The wavelet-denoising and wavelet-enhancement takes the wavelet decomposition and restructuring as the foundation, then the effect of wavelet decomposition and restructuring is closely related with the choice of wavelet base. Therefore, comprehensively compared the commonly used wavelet base both from the theory and experiment view, and indicated the wavelet base which most matches with the above application.
