摘要 提要:将一种基于交叉验证理论的小波滤波算法引入到CCD图像采集系统中,实验表明,与一些传统的方法相比,这种小波滤波方法滤除了原图中的大量噪音并显著提高了信噪比,积分重心偏差较小。 A wavelet algorithm based on cross- validation theory was introduced to the image collection system of CCD, and the experimental results showed that some noises were removed, and the image of better SNR quality and smaller variance of integral barycenter was obtained.
