Enhancing Quality for HEVC Compressed Videos [PDF]

IEEE transactions on circuits and systems for video technology (Print), 2017
The latest High Efficiency Video Coding (HEVC) standard has been increasingly applied to generate video streams over the Internet. However, HEVC compressed videos may incur severe quality degradation, particularly at low bit rates.

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 ...

A Comprehensive Survey of Adaptive Streaming Over HTTP (DASH) in 5G Networks: Performance Enhancements and Emerging Challenges

Advances in Multimedia, Volume 2026, Issue 1, 2026.
Dynamic adaptive streaming over HTTP (DASH) has emerged as a foundational technology for video delivery over heterogeneous networks, particularly within 5G environments characterized by high bandwidth variability, ultralow‐latency requirements, and dense mobility patterns.

Foliar application of humic liquid extract from vermicompost improves garlic (Allium sativum L.) production and fruit quality

International Journal of Recycling of Organic Waste in Agriculture
Purpose The beneficial effects of liquid humus applied to plants are well reported in the literature; however, studies of liquid humic application in the production and quality of garlic culture are practically nonexistent. The objective of this work was

A Convolutional Neural Network Approach for Post-Processing in HEVC Intra Coding [PDF]

Conference on Multimedia Modeling, 2016
Lossy image and video compression algorithms yield visually annoying artifacts including blocking, blurring, and ringing, especially at low bit-rates. To reduce these artifacts, post-processing techniques have been extensively studied. Recently, inspired

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 ...

HEVC saliency map computation

Electronic Imaging, 2016
This paper investigates whether the information related to the human visual saliency is still preserved at the level of the HEVC compressed stream syntax elements. In this respect, a new saliency model, matched to the peculiarities of this emerging standard is defined.

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.
