Abstract :
In real engineering application, sampling signals are inevitably influnenced by noise.Based on the characteristic analysis of signal noise, we know that the wavelet analysis was effective when applied to eliminate noise . Simulations are performed on these algorithms in this paper, and the simulations demonstrate that the results of denoising by wavelet packet may better or less than wavelet because of the different amount of noise in image.
