In the near future, certain 2D (2 Dimensional) video application scenarios are likely be replaced by 3D (3 Dimensional) video, in order to achieve a more involving and immersive representation of visual information, and to provide more natural methods of communication. Stereoscopic video is the simplest form of 3D video, which renders two slightly different views of a scene to perceive the dept...

This paper integrates Octagon and Square Search pattern (OCTSS) motion estimation algorithm into H.264/AVC (Advanced Video Coding) video codec in Adaptive Group of Pictures (AGOP) mode. AGOP structure is computed based on scene change in the video sequence. Octagon and square search pattern block-based motion estimation method is implemented in inter-prediction process of H.264/AVC. Both these ...

BACKGROUND There are no systemic therapies approved in the United States to treat pediatric psoriasis. OBJECTIVE We sought to evaluate long-term safety and efficacy of etanercept in children and adolescents with moderate to severe plaque psoriasis. METHODS This 5-year, open-label extension study enrolled patients aged 4 to 17 years who had participated in a 48-week parent study. End points ...

The primary advantage of the H.264 video compression technique is the ability to provide good video quality at substantially lower bit rates compared with other video compression methods. This is due to the use of variable block sizes, multiple reference frames, and the consideration of Rate-Distortion Optimization (RDO). However, these features come with the price of added complexity due to th...

The H.264/AVC (ISO/IEC MPEG-4 Part 10) video coding standard (Wiegand & Sullivan, 2003), which was officially issued in 2003, has become a challenge for real-time video applications. Compared to the MPEG-2 standard, it gains about 50% in bit rate, while providing the same visual quality. In addition to having all the advantages of MPEG-2 (ITUT & ISO/IEC JTC 1, 1994), H.263 (ITU-T, 2000), and MP...

Moving object segmentation in compressed domain plays an important role in many real-time applications, e.g. video indexing, video transcoding, video surveillance, etc. Because H.264/AVC is the up-to-date video-coding standard, few literatures have been reported in the area of video analysis on H.264/AVC compressed video. Compared with the former MPEG standard, H.264/AVC employs several new cod...

Phenobarbital-responsive DNA elements were identified in the 5'-flanking region of the chicken CYP2H1 gene by in reporter gene assays in a chicken hepatoma cell line (leghorn male hepatoma (LMH)). A 264-base pair (bp) enhancer sequence (phenobarbital-responsive unit (PBRU)) responded to phenobarbital and a variety of phenobarbital-type inducers. Analysis of putative transcription factor binding...

One of the top tasks for video streaming, video surveillance, video conferencing and video broadcasting is a low bit rate and real-time video coding. The most popular low bit rate video compression approach is based on the H.264/AVC standard [1]. This standard provides high compression efficiency due to hybrid video coding which includes intra-frame prediction, variable-size block motion estima...

Video encoding for multimedia services over communication networks has significantly advanced in recent years with the development of the highly efficient and flexible H.264/AVC video coding standard and its SVC extension. The emerging H.265/HEVC video coding standard as well as 3D video coding further advance video coding for multimedia communications. This paper first gives an overview of the...
