摘　　要：根据二代小波变换的基本理论和特点,研究二代小波对图像去噪的效果。提出基于二代小波的尺度适应性分解算法,并使用改进阈值函数进行阈值分析后再对噪声图像进行去噪处理。实验结果证明,使用尺度适应性二代小波对图像去噪比其他方法具有更好的效果,去噪后的图像信噪比大大提高。Study a novel algorithm of Scale-adaptive Second generation Wavelets in image de-noising. The basic theory and characters of the Second generation Wavelets are introduced in this article and Scale-adaptive decomposition algorithm has been developed based on the Second generation Wavelets. The noisy image was dealed with the Improved threshold value function. , and the experiments show that the proposed algorithm is efficient in image de-noising.
