中文摘要：

超分辨率复原技术的目标是提高图像的空间分辨率,而高动态范围（HDR,high dynamic range）图像合成技术能够增强图像表达高对比度场景的能力。将两者结合起来进行高分辨率和高动态范围图像联合重建的研究,对高质量图像信息的获取具有重要的意义,可满足广泛的多媒体应用的需求。对高分辨率与高动态范围图像联合重建研究进展进行梳理,分析其基本思想的产生、发展以及存在的难点,并进一步提出在基于学习的框架内进行联合重建的思路。

英文摘要：

The goal of super resolution is to improve the spatial resolution of a image,while high dynamic range imaging algorithms can enhance the ability to describe the high contrast scenes in a image.The joint reconstruction study of both the high dynamic image and super resolution reconstruction has the great significance for the acquisition of the high quality image and can meet the needs of many multimedia applications.The progress in this area is investigated,the basic ideas and the difficulties in the implementation are analyzed.Furthermore, a framework of learning based joint reconstruction is proposed.
