| 摘 要： | 为了去除图像中的噪声,文章利用图像分块的思想,结合阈值去噪法和最小均方误差估计(MMSE),给出了一种基于领域阈值的小波域图像去噪算法。该算法与经典的子带自适应阈值去噪法BayesShrink算法相比,本文算法在峰值信噪比和视觉效果上都好于BayesShrink算法。

| Abstract: | In order to remove noise in the image,in this paper,a wavelet image denoising algorithm based on domain threshold is proposed,which by exploiting the idea of image piecemealed,and combining the threshold denoising method with the minimum mean squared error.This algorithm compared with classical sub-band adaptive algorithms BayesShrink algorithm,it has better effect in peak signal to noise ratio and visual quality. |
