Nonlinear Transform Coding for VVC Intra Coding

2024 Picture Coding Symposium (PCS)
Modern hybrid video codecs like Versatile Video Coding (VVC) heavily rely on transform coding tools. Given a prediction signal at the encoder, the residual is transformed using trigonometric transforms.

Multiple direct mode for intra coding

2017 IEEE Visual Communications and Image Processing (VCIP), 2017
In this paper, a multiple direct mode (MDM) method is presented for chroma intra coding. The main contributions of the proposed MDM method include two aspects: selection of multiple luma intra prediction modes from co-located luma blocks, and the derivation of chroma intra prediction modes from spatial neighbouring blocks.

On the coding gain of intra-predictive transforms

2009 16th IEEE International Conference on Image Processing (ICIP), 2009
Intra-predictive transforms are a kind of block-based transforms that can exploit both the intra- and inter-block correlations. This paper analyzes the coding gains of intra-predictive transforms for the Gaussian process. The tight upper bound of the coding gain is derived, which is shown to be better than both the discrete cosine transform and the ...

Fast PU Intra Mode Decision in Intra HEVC Coding

2019 Data Compression Conference (DCC), 2019
As an upgrade for H.264/AVC, high efficiency video coding (HEVC) achieves 50% bitrate reduction under the equivalent visual quality. However, high computational complexity increases dramatically for adopting up to 35 intra prediction modes. To deal with this issue, we explore spatial-temporal correlation between PUs to narrow rough mode decision (RMD ...
