—High Efficiency Video Coding (HEVC) is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards—in the range of 50% bit-rate(More)
This paper provides an overview of the intra coding techniques in the High Efficiency Video Coding (HEVC) standard being developed by the Joint Collaborative Team on Video Coding (JCT-VC). The intra coding framework of HEVC follows that of traditional hybrid codecs and is built on spatial sample prediction followed by transform coding and postprocessing(More)
T HE FIRST commercially successful digital video compression standard emerged 20 years ago in the form of Recommendation ITU-T H.261. MPEG-1 and H.262/MPEG-2 video (the latter was jointly standardized by ITU-T and ISO/IEC) were then developed very soon thereafter, and they resulted in an explosion of products and services that created consumer video(More)
Coding efficiency gains in the new High Efficiency Video Coding (H.265/HEVC) video coding standard are achieved by improving many aspects of the traditional hybrid coding framework. Motion compensated prediction, and in particular the interpolation filter, is one area that was improved significantly over H.264/AVC. This paper presents the details of the(More)
Linear prediction model has been well investigated and applied in lossless image and video coding. In this paper, we investigate the linear prediction method for block-based lossy image coding and propose a method that merges linear prediction technique into H.264/AVC video coding framework. A block-based linear prediction method is designed instead of(More)
Recently, a flow-based selectin-dependent method for the capture and enrichment of specific types of cells (CD34+ hematopoetic stem and progenitor cells and human leukemia HL60) from peripheral blood was demonstrated. However, these devices depend on a monolayer of selectin protein, which has been shown to have a maximum binding efficiency as a function of(More)
This paper presents the feasibility of using an ad-hoc network as an infrastructure for a small group of inter-vehicle communication network. Mobile ad-hoc networking with wireless LAN infrastructure can be employed to build inter-vehicle communication based network. The irregular driving environment pose a challenge to the performance of a wireless LAN. We(More)
