摘　　要：超分辨率技术是当今图像处理领域的一个具有挑战意义的课题。在图像获取的过程中,受到成像条件以及成像方式的各种限制,成像系统不能获取原始图像场景中的全部信息。如何提高图像的空间分辨率一直以来都是图像处理领域的热点问题,图像超分辨率技术被认为是解决这一问题的有效方法。介绍了图像超分辨率复原的一般方法,以及国内外研究进展。Super-resolution technology is currently a challenging subject in the field of image processing. In the image acqui sition process, the imaging system cannot obtain the total information of the original image scene due to various restrictions of imaging conditions and imaging methods. Thus, the spatial resolution improvement research has been a hot topic in the field of image processing. Super-resolution technology is considered to he an effective way to solve this problem. This paper describes the traditional methods of image super-resolution restoration, and the research advances in recent years.
