Fast SHVC intra prediction mode decision implementation
Analog Integrated Circuits and Signal Processing, 2021The Scalable extension of the High Efficiency Video Coding standard (SHVC) combines the large compression efficiency and high visual quality of HEVC with the possibility of encoding several different versions of the same encoded video in a single bitstream. However, this comes at the cost of a high computational complexity.

Fast Intra Mode Decision for HEVC
2014 Tenth International Conference on Signal-Image Technology and Internet-Based Systems, 2014The intra prediction in HEVC exploits the new techniques, such as the tree coding structure and up to 35 intra prediction modes, etc., to achieve high coding efficiency but incur heavy computational complexity as well. To reduce the computational complexity, a novel fast mode decision algorithm for intra prediction in HEVC is proposed in this paper. In

H.264 can be coded with 7 different block sizes for motion-compensation in the inter mode, and various spatial directional prediction modes in the intra mode. To achieve as high a coding efficiency as possible, the H.264 encoder employs a complex mode decision technique based on rate-distortion optimization.
