Transform and Bitstream Domain Image Classification
P. R. Hill, D. R. Bull
Classification of images within the compressed domain offers significant benefits. These benefits include reduced memory and computational requirements of a classification system.…
Perceptually-inspired super-resolution of compressed videos
Di Ma, Mariana Afonso, Fan Zhang +1
Spatial resolution adaptation is a technique which has often been employed in video compression to enhance coding efficiency. This approach encodes a lower resolution version of th…
An adaptive Lagrange multiplier determination method for rate-distortion optimisation in hybrid video codecs
Fan Zhang, David R. Bull
This paper describes an adaptive Lagrange multiplier determination method for rate-quality optimisation in video compression. Inspired by the experimental results of a Lagrange mul…
Quality assessment methods for perceptual video compression
Fan Zhang, David R. Bull
This paper describes a quality assessment model for perceptual video compression applications (PVM), which stimulates visual masking and distortion-artefact perception using an ada…
A Subjective Study on Videos at Various Bit Depths
Alex Mackin, Di Ma, Fan Zhang +1
Bit depth adaptation, where the bit depth of a video sequence is reduced before transmission and up-sampled during display, can potentially reduce data rates with limited impact on…
VMAF-based Bitrate Ladder Estimation for Adaptive Streaming
Angeliki V. Katsenou, Fan Zhang, Kyle Swanson +3
In HTTP Adaptive Streaming, video content is conventionally encoded by adapting its spatial resolution and quantization level to best match the prevailing network state and display…
