AN IMPROVED DE-NOISING ALGORITHM BASED ON WAVELET MODULAR MAXIMUM

He Yonghong,Wen Hongyan and Jin Pengwei(Department of Civil Engineering,Guilin University of Technology,Guilin 541004)  
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.
