| 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。

| Abstract: | 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. |
