JVET-D0118 EE9: On adaptive scaling for extended colour volume materials [D. Rusanovskyy, D. Sansli, A. K. Ramasubramonian, J. Sole, M. Karczewicz (Qualcomm)]

Discussed in BoG JVET-D0192 (chaired by A. Segall)

This contribution reports preliminary results on adaptive scaling proposed in JVET-C0066 for coding of video with extended colour volumes, e.g. video in ST 2084/BT.2020 representation. The method was integrated to the JEM3.1 codebase and tested for selected HDR test sequences available for JVET development. Proposed algorithm was compared against the reference design in JVET-B0054 which was also ported to JEM3.1 and results were reported with BD-Rate for the tPNSRY and deltaE metrics.

It was proposed to AhG7 to formulate the Common Test Conditions for EE9 and continue study of the available in EE9 technologies in the next meeting cycle.

Preliminary results were presented. The contribution proposes to use the tPSNR and deltaE metrics, as well as visual evaluation.

The proponent recommended continuing study within AhG and/or EE.
