| 摘 要： | 提出一种基于改进型多尺度Retinex彩色图像的增强方法，以实现彩色遥感图像去薄云的新方法。采用改进型Retinex算法增强后的图像突出了黑暗区域的信息，但是云在遥感图像中出现在较亮区域时，一般来讲Retinex不能直接实现去云。如果将有云的遥感图像取补色，则原来亮的区域就变成了暗的区域。该文利用改进后的多尺度Retinex算法对这个区域实现增强，将黑暗的区域呈现出层次感，再将增强后的图像取补色，突出了原图像中亮区域的层次感，从而达到去除薄云的目的。实验结果表明:该方法去薄云效果良好。 |

| Abstract: | A novel thin cloud removal method based on advanced multiscale Retinex algorithm is suggested for color remote sensing image. Typically,the image enhanced by multiscale Retinex algorithm can provide the information in the shadow area,but the cloud in remote sensing image can not be removed directly by Retinex algorithm if it is in the bright region.This new method uses two complementary color operations between which the advanced multiscale Retinex algorithm is applied.The experimental result shows that the new method can remove the thin cloud in the image effectively and provide adequate information. |
