| Abstract: | In this paper, research of nonlinear image noise removal is based on Haar wavelets multiresolution analysis. We obtain thresholding bounds of image noise removal through wavelet shrinkage. The reconstruction of wave packets is reached. A better image noise removal is obtained by our experimental results as dual-low pass filter. |
