| Abstract: | Combining the method of threshold de-noising with scale tracking theory by Witkin,the improved de-nosing algorithm of Wavelet modular maximum can reject out the modular maximum value from the noise,and recover the signal efficiently.Compared with the traditional de-nosing methods by threshold value and translation invariance,the algorithm increases the signal to noise ratio. |

| Keywords: | wavelet modular maximum threshold value de-noising translation invariance deformation monitor |
