Abstract :
This paper introduces the principle of wavelet multi-resolution analysis. The wavelet threshold de-noising method is described. Some key problems on the wavelet threshold de-noising method are discussed in detail. The experimental results show that the wavelet threshold de-noising method can better preserve image details and its de-noising effect is better than that of the traditional filtering method.
