| 摘 要： | 该文提出了一种新的基于层间特性的多级小波收缩去噪算法．该算法根据图像小波系数的层间相关特性来确定各层的收缩阈值，并将这些收缩阈值用于图像去噪．实验表明：该算法比传统的算法能更有效地减少噪声，获得更高的PSNR．同时，新的算法还能减少高质量图像中的噪声．

| Abstract: | In this paper, we proposed a new multilevel wavelet shrinkage algorithm basing on inter-scale dependency for removal noise from the images. The shrinkage thresholds are determined by the inter-scale dependency. Experimental results show that this algorithm is superior to the classical wavelet shrinkage methods and receives higher PSNR. Furthermore, it can remove noise from the high quality images. |
