融合学习算法的单帧图像超分辨率复原

摘要

为从高度降质的单帧图像中重建出高分辨率图像，提出了一个结合自适应正则化与学习算法的超分辨率复原方法。该方法基于图像的局部特征，实现了正则化方法动态自适应控制过程，优化了学习算法中的训练集、预测原则和搜索过程，以降低基准图相关性要求、提高搜索效率。仿真实验分步论证了该方法的有效性，以及对复原效果的提升。%In order to reconstruct a high-resolution image from single highly blurred image, a super-resolution reconstruction method combined with adaptive regularization and learning algorithm is proposed. Based on local characteristics, the dynamic adaptive control progress of reconstruction method is achieved.
