Comparing temporal behavior of fast objective video quality measures on a large-scale database [PDF]

, 2016
In many application scenarios, video quality assessment is required to be fast and reasonably accurate. The characterisation of objective algorithms by subjective assessment is well established but limited due to the small number of test samples ...

High‐Fidelity Ultra‐High‐Definition Chroma Reconstruction in the Scaled YCbCr Colour Space via LUL0 Factorisation and Generalised Lifting

IET Image Processing, Volume 20, Issue 1, January/December 2026.
To enhance high‐fidelity chroma reconstruction, this paper introduces a scaled YCbCr colour space implemented via a novel analytical LUL_0 factorisation and generalised lifting schemes for exact integer reversibility. Experiments on 240 ultra‐high‐definition images demonstrate that this approach achieves an average colour peak signal‐to‐noise ratio ...

Can you tell a face from a HEVC bitstream?

, 2017
Image and video analytics are being increasingly used on a massive scale. Not only is the amount of data growing, but the complexity of the data processing pipelines is also increasing, thereby exacerbating the problem.

Secure Live Streaming: Implementing Security in Adaptive Video Streaming via Watermarking Techniques While Preserving Quality

International Journal of Digital Multimedia Broadcasting, Volume 2026, Issue 1, 2026.
The heterogeneity of the network at the edge creates unequal bandwidth availability for clients connected through diverse networks and devices. This variability can lead to bandwidth fluctuations and slow response times, resulting in buffering or degraded streaming performance.

SFNIC: Hybrid Spatial‐Frequency Information for Lightweight Neural Image Compression

CAAI Transactions on Intelligence Technology, Volume 10, Issue 6, Page 1717-1730, December 2025.
ABSTRACT Neural image compression (NIC) has shown remarkable rate‐distortion (R‐D) efficiency. However, the considerable computational and spatial complexity of most NIC methods presents deployment challenges on resource‐constrained devices. We introduce a lightweight neural image compression framework designed to efficiently process both local and ...

Adaptive Parallelization Based on Frame‐Level and Tile‐Level Parallelisms for VVC Encoding

Concurrency and Computation: Practice and Experience, Volume 37, Issue 25-26, 30 November 2025.
ABSTRACT To meet the growing demand for high‐efficiency video compression standards, Versatile Video Coding (VVC) has been developed as a successor to High Efficiency Video Coding (HEVC). VVC offers approximately a 50% reduction in bitrate compared to HEVC while maintaining comparable visual quality.

Survey of Inter‐Prediction Methods for Time‐Varying Mesh Compression

Computer Graphics Forum, Volume 44, Issue 1, February 2025.
This paper surveys existing methods for compressing time‐varying meshes (TVMs), focusing on the challenge of exploiting data redundancies due to varying connectivity and the absence of implicit correspondence information. We review current performance, available datasets, and potential future trends in the field.
