| Abstract: | The mechanism of a motion-blurred image generated from aerial imaging system was introduced. The mathematical model of motion-blurred image was established to give the point spread function of 2-dimensional motion blur,and the Wiener flter was utilized to remove image blur for aerial image. By the window technique,the edge error was restrained or reduced. The simulation results show that the Wiener filtering is effective in precision,which can get the restoration precision of 1 pixel. |
