Compression of integral 3D TV pictures
The development of a compression algorithm for reduction of the transmission bit rate of 3D integral TV pictures is discussed. The proposed full parallax 3D image compression algorithm takes advantage of the cross correlation between the multiple images recorded on a CCD placed behind a directionally selective microlens array as well as the correlation inherent within each image. Tests carried ...
متن کاملA novel coding scheme for full parallax 3D-TV pictures
A unique integral imaging system is employed as part of a three dimensional television system, allowing display of full colour 3D images with continuous parallax within a wide viewing zone. A significant quantity of data is required to represent captured integral 3D images with adequate resolution. In this paper a lossy compression scheme is described, based on the use of a three dimensional di...
متن کاملError concealment techniques for digital TV
Compressed video bitstreams are intended for real-time transmission over communication networks. Most of the video coding standards employ the temporal and spatial prediction structure to reduce the transmitted video data. Therefore, the coded video bitstreams are highly sensitive to information loss and channel errors. Even a single bit error can lead to disastrous quality degradation in both ...
متن کاملNew Bi-prediction Techniques for B Pictures Coding
In the conventional video codec, B pictures usually employ five prediction modes, including bi-prediction, direct prediction, forward prediction, backward prediction and intra modes. Among them, the direct and bi-prediction modes, whose prediction values are achieved from both forward and backward reference pictures, are more efficient in exploiting the temporal correlation between the referenc...
متن کاملMining TV Broadcasts 24/7 for Recurring Video Sequences
Monitoring and analyzing TV broadcasts is an important task in the media as well as the advertising business. An important subtask is the frame-accurate detection of recurring video sequences. Examples of recurring video sequences are commercials, channel advertisements, channel intros, and newscast intros. Most of these different kinds of repeating video clips can automatically be classified b...
