Versatile Video Coding Using Discrete Wavelet Transforms and Histogram Analysis

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This paper proposes a novel framework that combines discrete wavelet transforms (DWT) and histogram analysis to optimise the prediction directions in VVC. Through selective reduction of prediction directions based on dominant texture orientation and minimising residual energy, the frame‐work achieves enhanced computational efficiency while maintaining ...

Adaptive Bitrate Streaming With Video Quality Enhancement

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We bring the new factor, DVQE sensitivity, into the bitrate selection for the QoE improvement of adaptive video streaming. We develop DSABR, which selects chunk bitrate with high DVQE sensitivity to improve video quality as well as reduce bandwidth usage, thereby achieving efficient performance in bandwidth‐constrained network environments.

A TEFSM-based Framework for QoE Evaluation of OTT Services

Труды Института системного программирования РАН, 2018
Most of the work related to QoE maps objective variables (QoS-related) into a single one that predicts the quality the user perceives. In this paper we present a new approach to model multimedia OTT services, integrating not only the functional aspects ...
