摘要
超分辨率图像复原的目的在于复原截止频率之外的信息,以使图像获得更多的细节和信息。基于互有位移序列图像进行的超分辨率复原,除了利用物体的先验信息和单幅图像的信息之外,还充分利用了不同图像之间的补充信息,因此其超分辨率复原能力高于利用单帧图像的复原法。这项技术可以广泛应用于遥感、高清晰电视和医学成像等多个领域。通过对超分辨率复原技术理论基础的阐述,指出基于序列图像的高分辨率成像技术的合理性,并介绍对互有位移图像序列的获取方法:亚像元动态成像系统、光学系统和利用压电陶瓷的方法。
The super-resolution image restoration can reconstruct the information over the cut-off frequency to get more details of image.Super-resolution restoration based on the image sequences with displacement take advantage of the supplemental information of different images besides the prior information and the information of single images,so the restorative ability is better than beofre.The technique is widely used in remote-sensing,high-definition television(HDTV),standard and medical imaging,etc.The theories of super-resolution for imaging restoration are explained.Meanwhile the rationality of high-resolution technique based on image sequence is introduced.The methods of image capture-subpixel dynamic imaging system,optical system and the piezoelectric based method are introduced.
