Abstract: The images are always influenced by noise when it is obtained and transmitted, which causes too big difference between the image data and the realistic. To fast and effectively eliminate these noise signal, this article Bisected elimination noise's method scene and discussed many kinds of mixed noise image intensification processing technologies based on the wavelet packet transformation. The experiment indicated that our method in image denoising processing is effective and feasible.
