Abstract
This paper presents recommended techniques for choosing video sequences for subjective experiments. Subjective video quality assessment is a well-understood field, yet scene selection is often driven by convenience or content availability. Three-dimensional testing is a newer field that requires new considerations for scene selection. The impact of experiment design on best practices for scene selection will also be considered. A semi-automatic selection process for content sets for subjective experiments will be proposed.
Highlights
Advances in the consumer video market include higher resolution (Full-HD, 4K, 8K), additional dimensions and reconstruction precision (three-dimensional (3D), high dynamic range, wide color gamut), associated media (audio wavefield synthesis, emotive devices), and interaction methods (mobile phones, social networks, see-through glasses with augmented reality)
Advances in the consumer video market include higher resolution (Full-HD, 4K, 8K), additional dimensions and reconstruction precision (three-dimensional (3D), high dynamic range, wide color gamut), associated media, and interaction methods
The correct selection of scene pools for subjective experiments has been previously mostly limited by content availability
Summary
Advances in the consumer video market include higher resolution (Full-HD, 4K, 8K), additional dimensions and reconstruction precision (three-dimensional (3D), high dynamic range, wide color gamut), associated media (audio wavefield synthesis, emotive devices), and interaction methods (mobile phones, social networks, see-through glasses with augmented reality). We first describe guidelines for scene selection for traditional, entertainment-oriented tests that were developed using over two decades of experience in designing video quality subjective tests. Basic scene selection Entertainment-oriented subjective video quality tests try to represent a wide range of entertainment content in a scene pool containing approximately eight to ten clips.
