| 摘 要： | 对于多帧超分辨率技术而言,最理想的情况是让高分辨的图像包含低分辨序列中所有信息。因此,序列各帧之间的差异信息,即非冗余信息,对于超分辨率重建而言有着非常重要的作用。然而,序列各帧在时空域有很强的相关性,非冗余信息相对于冗余信息十分微弱,难以直接提取。提出了一种改进超分辨率算法,提取并单独处理非冗余信息,再将其融合入超分辨率结果图像中,使超分辨率图像最大限度的保留低分辨序列中的非冗余信息。试验表明:该算法性能较为优异。

| Abstract: | For multi-frame super resolution reconstruction technology,the perfect result is combing all the information contained in low resolution sequence.So,the difference information between the frames,namely,the non-redundant information,is very important.However,the frames of sequence has strong correlation in the spatial-temporal domain.The non-redundant information is very dim compared with the redundant information,and it is difficult to separate.This paper proposes an improved super-resolution algorithm to separate and process the non-redundant information.Many experiments reveals that the performance of this algorithm is excellent. |
