【 摘 要 】

"An error is generally introduced when animage is taken remotely by an imaging system, This is more prominentwhen an airborne system takes the image of the earth's surface.Generally the error, known as geometric error, is a composite oftranslation, rotation, scaling, and warping of the image. This paperdiscusses an algorithm to remove geometric error by applying geometrictransformation and registering an image with its reference image, or thesame image taken at some other instance of time. To remove these highlyirregular distortions, translation, rotation, scaling, and warping tothe image is applied simultaneously. This is done by establishing apolynomial affine transformation, which is applied to the image withgeometric error to register it with the reference image, thus removingthe error
