高动态范围成像（HDRI）的主要目标是在从采集到显示的图像和视频处理的所有阶段，在强度水平和色域方面精确再现真实的世界外观。在我们的工作中，我们研究了有损HDR图像和视频压缩的问题，并提供了一些新的解决方案，这些解决方案针对存储效率或与现有压缩标准的向后兼容性进行了优化。为了利用HDR信息，即使对于传统的低动态范围显示器，我们设计色调映射算法，其将场景中的HDR对比度范围调整为典型显示设备中可用的范围。
The main goal of High Dynamic Range Imaging (HDRI) is precise reproduction of real world appearance in terms of intensity levels and color gamut at all stages of image and video processing from acquisition to display. In our work, we investigate the problem of lossy HDR image and video compression and provide a number of novel solutions, which are optimized for storage efficiency or backward compatibility with existing compression standards. To take advantage of HDR information even for traditional low-dynamic range displays, we design tone mapping algorithms, which adjust HDR contrast ranges in a scene to those available in typical display devices.
