High Frame Rate Video

As the demand for higher quality and more immersive video content increases, the need to extend the current video parameter space of spatial resolutions and display sizes, to include, among other things, a wider colour gamut, higher dynamic range…

What’s on TV: A Large-Scale Quantitative Characterisation of Modern Broadcast Video Content

What does one year of modern broadcast video look like? This project analyses the spatial and temporal diversity in contemporary video to make inferences about testing new video technologies.

Optimal presentation duration for video quality assessment

Does the length of a video sequence affect the reliability of a viewer’s quality assessment? With the aim of increasing data collection efficiency and reducing processing times, this project aims to identify how long video sequences should be in subjective video quality assessment studies.

Perceptual Quality Metrics (PVM)

Novel video quality metrics that use the dual-tree complex wavelet transform (DT-CWT) and motion analysis to characterise perceptual tolerances within spatial and temporal textures

Parametric Video Coding

A video compression scheme where an analysis/synthesis framework is employed rather than the conventional energy minimization approach.

Parametric Video Compression

This project presents a novel means of video compression based on texture warping and synthesis. Instead of encoding whole images or prediction residuals after translational motion estimation, our algorithm employs a perspective motion model to…
