Title:
- Luma HDRv: an open source high dynamic range video codec optimized by large-scale testing
Presenter(s)/Author(s):
Abstract:
We present Luma HDRv — an open source solution for encoding of high dynamic range (HDR) video. The software makes use of techniques for adapting the HDR video for compression with a standard video codec. In the design of the encoder we perform a large-scale test, using 33 HDR video sequences in order to compare 2 video codecs, 4 luminance encoding techniques (transfer functions) and 3 color encoding methods. This serves both as an evaluation of existing techniques for encoding of HDR luminances and colors, as well as to optimize the performance of Luma HDRv.
