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 ...

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 ...
