Video summarization refers to an important set of abstraction techniques aimed to provide a compact representation of the video essential to effectively browse and retrieve video content from multimedia repositories.
Most of these video summari[...]

Several specific features have been incorporated into Motion estimation (ME) in H.264 coding standard to improve its coding efficiency.
However, they result in very high computational load. In this paper, a fast ME algorithm is proposed to redu[...]

This paper addresses video transcoding from H.264/AVC into MPEG-2 with reduced complexity and high rate-distortion efficiency.
While the overall concept is based on a cascaded decoder–encoder, the novel adaptation methods developed in this work[...]

In this paper, we first develop a simple but nevertheless accurate and fully analytical model for the sequence-level distortion–rate (D–R) performance of predictive video source encoding.
This model focuses on the input–output behavior of the s[...]

Joint video/depth rate allocation is an important optimization problem in 3D video coding.
To address this problem, this paper proposes a distortion model to evaluate the synthesized view without access to the captured original view.
The propo[...]

AVS (audio video coding standard) is the latest multimedia coding standard of China.
Similar to H.264/AVC, AVS adopted the technology of fractional-pel-accurate motion compensation, which enhanced the compression efficiency.
To obtain fraction[...]
