H.264 Based coding of omnidirectional Video
نویسندگان
چکیده
Omnidirectional video is an adequate image-based scene representation data format for interactive walkthroughs or surround viewing of a scene over the Internet. While efficient compression is a key issue in this context, the properties of omnidirectional video are not in line with the assumptions that are made about video sequences by modern compression standards like MPEG-4 AVC/H.264. We introduce a preprocessing approach which transforms omnidirectional video into a sequence of panoramic images before encoding. Using a state of the art MPEG-4 AVC/H.264 video coder, our approach performs up to 2dB better for low bit rates compared to regular encoding of omnidirectional video.

Video Abstraction in H.264/AVC Compressed Domain
Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...
متن کاملComparison of Stereo Video Coding Support in MPEG - 4 MAC , H . 264 / AVC and H . 264 / SVC
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 presents a novel H.264-based video coding scheme for a scalable delivery system which operates over heterogeneous networks and distributes real-time streaming video to diverse types of clients. The video coding scheme is a hybrid combination of discrete wavelet transform (DWT) and H.264. In the algorithm, an input video sequence is first decomposed into a fundamental sequence and a n...

Pattern-based video coding representing moving regions in macroblock has very good potential for improved coding efficiency over existing standard H.264/AVC in the very low bit-rate range. However, the coding efficiency diminishes compared to H.264 with the bit rates because variable block sizes of H.264 for motion estimation and compensation are successfully selected for any bit rates using we...

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...
