摘　　要：遥感图像处理中有许多正变换与逆变换处理，富立叶变换与逆变换、ＲＧＢ系统与ＩＨＳ系统之间的彩色空间变换以及主成分变换与逆变换就是典型的变换与逆变换处理技术。灵活地运用这些技术十分重要，分析了这些变换技术的特点，给出了在图像处理中的具体应用实例。There are so many transform and ant-transform methods in remote sensing image pro-cessing. Forier transform,K-L transform,RGB-IHS color space transform and their ant-transforms are typical ones. This paper presents one idea that how to use transform andant-transform method to get good image processing results. This paper gievs some exam-ples about these methods applicating in remote sensing processing.Obviously,we can useForier transform and its ant-transform to reduce or desminish image noise;RGB-IHS colorspace transform and ant-transform to composite with different spatial resolution images etc.
