高动态范围成像研究进展

Recent research in high dynamic range imaging

高动态范围成像技术是近年来图像处理、计算机图形学等领域的研究热点。基于高动态范围成像技术的主要流程,从高动态范围场景的捕获、高动态范围图像的合成、色调映射、当前高动态范围成像技术遇到的挑战以及高动态范围成像的发展趋势等5个方面,综述高动态范围成像技术的研究进展。

High dynamic range（HDR）imaging can precisely capture the scene irradiance,which has been a hot research topic in image processing and computer graphics for two decades.Based on the main flow of HDR imaging,the recent research and advances in HDR imaging are reviewed in detail,including the methods of capturing HDR scenes,the ways to combine exposurebracketed images into an HDR image,tone mapping,the challenges and the development trend in HDR imaging.
