中文摘要：
针对基于迭代反投影（IBP）算法的视频超分辨率重建，提出了一种改善初始估计来提高重建效果的方法．本文采用小波局部适应插值得到初始估计，结合滑动窗的视频重建模型，由一段低分辨率的视频重建一段高分辨率的视频，达到提高视频空间分辨率的目的．实验表明改进算法得到的高分辨率视频有更好的视觉效果．
英文摘要：
For the video super-resolution reconstruction based on iterative back projection （IBP） algorithm, an improved method by raising the initial guess for improving reconstruction quality is proposed. Firstly a better initial guess is performed with wavelet-local adaptation interpolation. Then Combined with segmentation reconstruction model, a super-resolution video is reconstructed from a low-resolution video associated with the promotion of spatial resolution. At last the experimental results show that the reconstructed super-resolution video has better visual effect.
