摘要

With the development of Wavelet Theory in Image Processing, persons developed all sorts of wavelet de-noising algorithms. Especially, Lifting scheme which is the basis constructed tool for the second generation wavelet and it makes us interpret the basis theory in a simple method is commended by JPEG 2000, persons put more attention to use it to image processing. This paper first described the principle of several wavelet de-noising algorithms and compared with these algorithms. Based on these, the paper gives three kinds of improved methods at last. The simulation experiment shows that it is effective for image de-noising.
