摘要
针对传统重构算法不能很好地解决压缩视频的超分辨率图像重构的问题,文中提出了一种基于凸集投影(POCS)理论的压缩视频超分辨率重构算法。整个算法是在严格数学推理基础上形成的,具有较强的逻辑性和严密性。实验结果也表明,该算法不仅在峰值信噪比(PSNR)值和重构效果对压缩视频有较大提高和明显改善,而且易于扩展,具有广泛的应用范围。
In this paper,a new algorithm of compressed video super - resolution restoration based on POCS theory is proposed to resolve the problem of the traditional restoration methods cannot be well applied to the compressed video. The total algorithm is formulated by rigorous reasoning,and the results of the experiment demonstrate that the algorithm not only more great than the traditional ones on the aspects of PSNR and restoration effect,but also has the characteristic of easy extension.
