Method of Wavelet Threshold Denoising Based on Mean Denoising

Wavelet threshold denoising methods are analyzed and compared.The mean denoising method and the threshold denoising method are combined to be an improved method-method of wavelet threshold denoising based on mean denoising,With this method,the wavelet coefficients not only have good continuity and high accuracy but also have a better denoising effect.The simulation results show denoising effects are clearly improved.
