| 摘 要： | 提出一种CR医学图像的小波阈值去噪算法．对含噪图像进行小波分解得到图像的小波系数，采用文中提出的阈值算法对系数进行去噪处理，根据处理后的系数重建CR图像。实验结果表明该方法能有效的去除CR图像的噪声．较好的保留医学诊断所需要的图像细节。

| Abstract: | A wavelet threshold denoising algorithm for CR images is put forward here. A noised CR image is decomposed into wavelet coefficients, which are processed by the algorithm, and the denoised CR image is reconstructed based on the processed coefficients. Examples are too presented to demonstrate the efficiency of the algorithm on denoising and maintaining the detail of the CR images. |
