Improved Wavelet Algorithm on Image Denoising Processing
Wavelet image de-noising has been well acknowledged as an important method of de-noising in Image Processing. Lifting scheme is not only a fast algorithm of existing wavelet transforms, but also a tool to produce new wavelet transforms. In this paper, the principle of several wavelet de-noising algorithms are described, and we compares with these algorithm, gives three kinds of improved algorithm. The simulation experiment shows that it is practicable and effective.
