Abstract: Due to the long distance between satellite camera and the site, the resolution of remote sensing image is low. In order to get high resolution image, Image Analogies (IA) technology and cubic convolution interpolation algorithm were combined, and a new idea that studied the highfrequency details of the high resolution image directly in the learning set was proposed. The experimental results show that this method can not only amplify images much more sharply, but also generate more reasonable details to enhance the image than general image analogies method. Thus, the amplified remote sensing image becomes more vivid.
