Abstract: A new super resolution reconstruction approach on periodic video is proposed. It reconstructs one period clear video from a long video with several periods. Firstly, it aligns the video by the detected periods and groups the frames. Then each high resolution image in one period can be reconstructed by the frames which the object poses in the same position. For enhancing image resolution from multi-frames, it proposes a direct computation method which is different from the iterative model based approaches such as back-projection approaches etc. which had been proposed. Experiments on simulation images and real images show that the approach is better than other model based super resolution methods.
