| 为便于线阵CCD(Charge-Coupled Device)全景图像的后期运算处理,需要对图像进行去噪处理,以提高图像信噪比。分析了线阵CCD扫描全景成像系统中图像噪声的来源,研究了该系统噪声的特性。对比研究基于小波变换的多种去噪算法的优劣性和使用条件,提出一种基于小波软硬阈值的中值滤波去噪方法。通过实验结果分析,验证了该方法具有更好的可靠性和有效性,适用于线阵CCD全景图像的去噪处理。 |

| For the purpose of improving convenience for the image processing of the panorama system based on linear CCD(Charge-Coupled Device) , de-noise the images to improve the SNR is needed . Analyzed the source of noise of the images grabbed by the panorama system, studied characteristic of the noise. Comparing the advantages and disadvantages of multiple methods of de-noising, a mean -value method of image de-noising based on wavelet soft-and-hard threshold is presented. By analyzing the experiment results, proved the reliability and availability of this method, adopted to the de-noising processing of the panorama. |
