摘要
图像超分辨率是指从一序列低分辨率观测图像中重建高分辨率图像。图像超分辨率充分利用了各帧图像间相似而又不同的信息。该技术可以广泛应用于遥感、医学成像和高清晰度电视等多个领域。从图像超分辨率的含义、发展现状、主要技术方法和未来研究展望等方面,对图像超分辨率复原领域的研究进行了综述。
Super-resolution image restoration is a technique for reconstructing a high-resolution image （or sequence） from an image sequence of low-resolution observation. Super-resolution makes full use of the similar, but not the same, information among each observation. This technique is widely used for remote-sensing, medical imaging, and high-definition television （HDTV） standard, etc. This paper gives an overview of super-resolution in terms of the mainly used techniques. With the present problems in this area, the paper gives some work and open issues that can be researched more in the future.
