Perceptually Enhanced Multimedia Data Acquisition, Processing, Transmission and Visualization

沿着从数据采集到可视化的处理流水线来阐述人类感知标准沿着可以向用户递送更好的视觉体验。尽管在高清晰度技术方面取得了最新的进展，但数字显示设备所支持的动态范围仍然不足以匹配人类视觉系统所感知的自然场景中的亮度的物理范围。光度测量设备只能捕获这种自然光谱的一个子集。因此，挑战在于编码光变化跨越该子集的场景。这可以通过以不同曝光获取多个图像来部分解决，所述多个图像融合成一个最终高动态范围（HDR）图像，所述最终高动态范围（HDR）图像然后经历映射过程并输出到低动态范围显示器以供人类观看者使用。

Incorporating human perceptual criteria along the processing pipeline from data acquisition to visualization can deliver better visual experience to users. Despite the latest advances in high definition technology, the dynamic range supported by digital display devices is still insufficient to match the physical range of luminance in natural scenes as perceived by the Human Visual System. Photometric equipment can only capture a subset of this natural spectrum. Thus, the challenge lies in encoding a scene where light variation spans beyond this subset. This can be partly addressed by acquiring multiple images at different exposures, fused into one final High Dynamic Range (HDR) image, which then undergoes a mapping process and is output to Low Dynamic Range displays for human viewers.
