Lagrangian method based Rate-Distortion Optimization revisited for dependent video coding

Video encoding is based on the DPCM framework where temporal prediction coding introduces Rate-Distortion (RD) dependence. The RD operating point of the current unit depends on the particular choices of RD points of its reference units. …

Shot boundary detection using convolutional neural networks

Video shot boundary detection (SBD) is necessary for further video analysis like video retrieval and annotation. Great efforts have been made to develop SBD algorithms for speed and accuracy. Most works implement frame histogram as features to …

Systemic view on service management in Shanghai World Expo

We will introduce our research on the service management in Shanghai World Expo from systemic view. We not only care the general queuing phenomena in the physical aspect, but also the psychological aspect in visitors and volunteers. Finally we wish …

Improving flexible macroblock ordering of H.264/AVC

H.264/AVC is the latest video coding standard from ITU-T. It provides superior and efficient video coding at low bit rates. Flexible macroblocks ordering (FMO) is an error-resilient tool included in H.264/AVC. In this paper, a novel technique for …
