In this paper, a new algorithm of compressed video super-resolution restoration based on Bayesian estimation is proposed to resolve the problem of the traditional restoration methods which cannot be well applied to the compressed video.
针对传统算法不能很好解决压缩视频的超分辨率图像重构问题,提出了一种基于Bayesian估计的压缩视频超分辨率重构算法。
At first an acquisition of the compressed video model is proposed,then the super-resolution problem is for mulated within the Bayesian framework and the MAP(maximum posterior probability) criterion,finally a universal solution of the problem is presented by integrating the CCD(cyclic coordinate decent) with SA(successive approximations).
为了对视频进行更有效的压缩,首先建立起一个从原始图像到压缩视频的成像模型,然后在此模型基础上运用Bayesian估计理论,在最大后验概率准则下表述该问题;最后通过综合使用CCD(cyc lic coord inate decent)和SA(successive approxim ations)等方法从理论上给出了压缩视频超分辨率重构问题的一般解决方法,同时针对成像过程中原始高分辨率图像的降质函数一般为未知的情况,提出了一种基于EM(expectation-m axim ization)算法的降质函数的确定方法。
