High Dynamic Range Video Compression Exploiting Luminance Masking

Lossy compression of high dynamic range images and video

Most common image and video formats have been designed to work with existing output devices, like LCD or CRT monitors. As display technology makes progress, these formats no longer represent the data that new devices can display. Therefore a shift towards higher precision image and video formats is imminent. To overcome limitations of common image and video formats, such as JPEG, PNG or MPEG, w...

Algorithms for compression of high dynamic range images and video

High Dynamic Range Image and Video Data Compression

Although high dynamic range (HDR) image and video are becoming common in many computer graphics applications, their data compression has received little attention so far. In this paper, we propose a practical approach to HDR video compression for efficient storage and fast transmission. Most current HDR images and videos are created from multiple exposures of the scene with varying exposures or...

Objective and subjective evaluation of High Dynamic Range video compression

A number of High Dynamic Range (HDR) video compression algorithms proposed to date have either been developed in isolation or only-partially compared with each other. Previous evaluations were conducted using quality assessment error metrics, which for the most part were developed for qualitative assessment of Low Dynamic Range (LDR) videos. This paper presents a comprehensive objective and sub...
