This document describes the core experiment CE6 on HDR post processing approaches. The CE relates to HDR and WCG video coding technologies and focuses on the reconstruction of an HDR video with the output decoded video from an HEVC Main 10 decoder.
In this CE, only solutions that operate as pre-processing to the encoder and post-processing to the main10 decoder are considered.
The tested technologies may require metadata which is signaled through VUI/SEI and is not utilized in a normative reconstruction process of the decoder. Post-processing may be performed on decoded samples in 4:2:0 representation and/or on samples in 4:4:4 representation. In the spirit of being non-normative, the proposals in the CE should produce a "viewable" picture even if the metadata, if any, is lost.
