摘 要: 超分辨率图像处理技术是利用多帧关于同一场景的有相互位移的低分辨率降质图像来重建高分辨率高质量图像的技术。介绍了超分辨率图像处理技术的概念和起源;综述了超分辨率图像恢复研究现状。重点对单帧和多帧超分辨率图像处理的主要方法进行了评述,并总结对比了频域和空域方法的优缺点。最后对超分辨率图像处理技术的技术难点和前沿问题研究前景进行介绍和展望。 Super resolution image restoration(SR)is a new image processing branch, which restores higher resolution images from a sequence of degraded images with lower resolution. The concepts and research status of SR are summarized. And the main methods of super-resolution image processing of single frame and multi-frame are reviewed, especially the advantages and disadvantages of the frequency domain method and airspace method are summerized and compared.
