Section 2, Chapter H
SDR and HDR-colour metric for optimal colour-image quality (2025), Image part hers

Title: Visual and colourimetric properties for the SDR and HDR range;
Model for visual responses and optimizations
1. Introduction and goals.
2. Some colourimetric properties for the Standard Dynamic Range (SDR), and the High Dynamic Range (HDR).
3. Adjacent nd separate colour sample of different size.
4. Output linearization and threshold of the 9 step colour series N-WRGB.
5. Applications for an ergonomic image technology for the consumer area.
