Short-Distance Intra Prediction of Screen Content in Versatile Video Coding (VVC) [PDF]
IEEE Signal Processing Letters, 2018 A novel intra prediction algorithm is proposed to improve the coding performance of screen content for the emerging Versatile Video Coding (VVC) standard. The algorithm, called in-loop residual coding with scalar quantization, employs in-block pixels as reference rather than the regular out-block ones. To this end, an additional in-loop residual signal

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 ...
