WitrynaImproving chroma intra prediction for HEVC. YCbCr color space is widely used in previous video coding standards such as H.264 and the latest video coding standard … WitrynaAbstract The emerging intra-coding tools of High Effi- ciency Video Coding (HEVC) standard can achieve up to 36 % bit-rate reduction compared to H.264/AVC, but with significant complexity increase. The design challenges, such as data dependency and computational complexity, make it difficult to implement a hardware encoder for real- …

Witryna17 sie 2024 · Traditional intra prediction methods for HEVC rely on using the nearest reference lines for predicting a block, which ignore much richer context between the current block and its neighboring blocks and therefore cause inaccurate prediction especially when weak spatial correlation exists between the current block and the … Witryna6 sty 2016 · This paper proposes a new intra-mode decision method for HEVC. The proposed method makes use of the characteristics of some special modes that belong to both rough mode decision mode set and most probable mode set. It also improves the coding efficiency by adaptively applying different algorithms depending on the …
