Subjective assessment of the impact of a content adaptive optimiser for compressing 4K HDR content with AV1
Vibhoothi, Angeliki Katsenou, François Pitié +2
Since 2015 video dimensionality has expanded to higher spatial and temporal resolutions and a wider colour gamut. This High Dynamic Range (HDR) content has gained traction in the c…
Recommendations for Verifying HDR Subjective Testing Workflows
Vibhoothi, Angeliki Katsenou, John Squires +2
Over the past few years, there has been an increase in the demand and availability of High Dynamic Range (HDR) displays and content. To ensure the production of high-quality materi…
Comparison of HDR quality metrics in Per-Clip Lagrangian multiplier optimisation with AV1
Vibhoothi, François Pitié, Angeliki Katsenou +3
The complexity of modern codecs along with the increased need of delivering high-quality videos at low bitrates has reinforced the idea of a per-clip tailoring of parameters for op…
Filling the gaps in video transcoder deployment in the cloud
Vibhoothi, Daniel Joseph Ringis, Xin Shu +4
Cloud-based deployment of content production and broadcast workflows has continued to disrupt the industry after the pandemic. The key tools required for unlocking cloud workflows,…
Learnt Deep Hyperparameter selection in Adversarial Training for compressed video enhancement with perceptual critic
Darren Ramsook, Anil Kokaram
Image based Deep Feature Quality Metrics (DFQMs) have been shown to better correlate with subjective perceptual scores over traditional metrics. The fundamental focus of these DFQM…
