Abstract :
Because of motion, optical and sensor PSF, image resolution is usually not high in video image. To solve this problem this paper firstly proposes a model of image degradation. Then using the continuous frames which is taken from the same scene, it adopts the cubic spline interpolate method for motion compensation. After image registration, we make use of average filter to reconstruct the image. Lastly, we utilize Wiener filtering to eliminate blurring. The result indicates that compared with the original image the reconstructed image resolution is improved obviously.
