基于小波局部适应插值IBP算法的视频超分辨率重建
Video super-resolution reconstruction based on local-adaptation interpolation wavelet transform IBP algorithm
摘要
Abstract
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.关键词
