Wavelet and wavelet packet are both useful at denoising. Wavelet packet can depict the high frequency of the image more particularity. It has the better ability in analyze image. But it is not always better at denoising than wavelet. 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.
