Fast integer-pel and fractional-pel motion estimation for H.264/AVC
TL;DR: A hybrid Unsymmetrical-cross Multi-hexagon-grid Search (UMHexagonS) algorithm is introduced, which well solves the false motion vector estimation problem because of the local-minimum and can save 30–50% computation compared with the Full Fractional-pel Search scheme.

Towards Bandwidth Efficient Adaptive Streaming of Omnidirectional Video over HTTP: Design, Implementation, and Evaluation
TL;DR: The parameters and characteristics of a dataset for omnidirectional video are proposed and exemplary instantiated to evaluate various aspects of such an ecosystem, namely bitrate overhead, bandwidth requirements, and quality aspects in terms of viewport PSNR.
Journal ArticleDOI
Performance and Computational Complexity Assessment of High-Efficiency Video Encoders
TL;DR: It is shown that low-complexity encoding configurations, defined by careful selection of coding tools, achieve coding efficiency comparable to that of high- Complexity configurations.

TL;DR: The tests showed that bit rate savings of 59% on average can be achieved by HEVC for the same perceived video quality, which is higher than a bit rate saving demonstrated with the PSNR objective quality metric.

Fast Coding Mode Selection With Rate-Distortion Optimization for MPEG-4 Part-10 AVC/H.264
TL;DR: Two methods are proposed: early SKIP mode decision and selective intra mode decision that are verified to significantly reduce the entire encoding time by about 60% with only negligible coding loss.
