高动态范围(HDR)成像已经成为能够捕获和显示由人类视觉系统在真实的世界中感知的全范围照明的最重要的成像方法之一。已经开发了许多用于图像和视频的HDR压缩方法来处理HDR数据,但是它们中没有一个被采用作为选择的方法。特别地,总是保持允许在传统显示器上观看内容的一部分的流/图像的向后兼容的方法利用被开发以在传统显示器上观看HDR图像的色调映射算子。有大量的色调映射器,其中没有一个被认为是最好的,因为产生的图像可能被认为是主观的。这项工作提出了一种替代基于色调映射的HDR内容压缩,通过识别一个单一的曝光,可以再现最原始的HDR图像的信息。这种单次曝光可以适应任何传统编码器的位深度。任何可能丢失的附加信息都存储为残差。结果表明,与其他传统方法相比,质量也得到了保持,甚至更好。此外,所提出的方法是向后兼容的,实现简单,快速,并且不需要选择色调映射器或设置。
High dynamic range (HDR) imaging has become one of the foremost imaging methods capable of capturing and displaying the full range of lighting perceived by the human visual system in the real world. A number of HDR compression methods for both images and video have been developed to handle HDR data, but none of them has yet been adopted as the method of choice. In particular, the backwards-compatible methods that always maintain a stream/image that allow part of the content to be viewed on conventional displays make use of tone mapping operators which were developed to view HDR images on traditional displays. There are a large number of tone mappers, none of which is considered the best as the images produced could be deemed subjective. This work presents an alternative to tone mapping-based HDR content compression by identifying a single exposure that can reproduce the most information from the original HDR image. This single exposure can be adapted to fit within the bit depth of any traditional encoder. Any additional information that may be lost is stored as a residual. Results demonstrate quality is maintained as well, and better, than other traditional methods. Furthermore, the presented method is backwards-compatible, straightforward to implement, fast and does not require choosing tone mappers or settings.
