Intra Block-DPCM with Layer Separation of Screen Content in VVC Open

Mohsen Abdoli, Félix Henry, Patrice Brault, Fréderic Dufaux, Pierre Duhamel , et al. · 2019

An intra coding algorithm with layer separation is proposed. This algorithm is designed on top of an adopted tool in VVC, called Block DPCM (BDPCM), and benefits from texture information in a neighborhood to derive intensity levels of back…

Transform Coefficient Coding for Screen Content in Versatile Video Coding (VVC) Open

Mohsen Abdoli, Félix Henry, Patrice Brault, Fréderic Dufaux, Pierre Duhamel · 2019

Computer science Mathematics Physics

A transform coefficient coding scheme is proposed for 4 × 4 blocks in Versatile Video Coding (VVC), targeting screen content applications. The proposed algorithm, called Unary Bitplane Coding (UBC), uses unary codes of the coefficient ampl…

Short-Distance Intra Prediction of Screen Content in Versatile Video Coding (VVC) Open

Mohsen Abdoli, Félix Henry, Patrice Brault, Pierre Duhamel, Fréderic Dufaux · 2018

Computer science Mathematics

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-b…
