Image motion analysis and compensation algorithm for the frame-push-broom imaging spectrometer

In order to achieve the Restoration of motion-blurred image, a method based on Modulation Transfer Function (MTF) Image Regeneration is used in this paper. Firstly the degraded image is preprocessed, and then the MTF curve of the optical system is calculated. High frequency information of the image is restored according to the decreasing degree so as to increase the image resolution. For the high frequency of the degraded image frequency spectrum, the spectral image inverse FFT is conducted according to the some MTF decreasing pattern to restore the image. And an approximate restored image is obtained. In the simulation, with the above process, the restored image is acceptable for the requirement to improve.
