There exist a variety of ways to represent 3D content, including stereo and multiview video, as well as frame-compatible and depth-based video formats. There are also a number of compression architectures and techniques that have been introduced in recent years. This paper provides an overview of relevant 3D representation and compression formats. It also analyzes some of the merits and drawbacks...
For advanced 3D Video (3DV) applications, efficient data representations are investigated, which only transmit a subset of the views that are required for 3D visualization. From this subset, all intermediate views are synthesized from sample-dense color and depth data. In this paper, the method for reliability-based view synthesis from compressed multi-view + depth data (MVD) is investigated and corresponding...
Standard sleep stage classification is based on visual analysis of central (usually also frontal and occipital) EEG, two-channel EOG, and submental EMG signals. The process is complex, using multiple electrodes, and is usually based on relatively high (200-500 Hz) sampling rates. Also at least 12 bit analog to digital conversion is recommended (with 16 bit storage) resulting in total bit rate of at...
This paper presents a study on video plus depth compression using available MPEG standards and its optimization for mobile 3D services. Video plus depth enables 3D television, but as mobile services are subject to various limitations, including bandwidth, memory, and processing power, efficient compression as well as low complexity view synthesis is required. Two MPEG coding standards are applicable...
Different methods for coding of stereo video content for mobile 3DTV are examined and compared. These methods are H.264/MPEG-4 AVC simulcast transmission, H.264/MPEG-4 AVC Stereo SEI message, mixed resolution coding, and video plus depth coding using MPEG-C Part 3. The first two methods are based on a full left and right video (V+V) representation, the third method uses a full and a subsampled view...
This paper presents a study on different techniques for stereo video compression and its optimization for mobile 3D services. Stereo video enables 3D television, but as mobile services are subject to various limitations, including bandwidth, memory, and processing power, efficient compression is required. Three of the currently available MPEG coding standards are applicable for stereo video coding,...
Context-based adaptive binary arithmetic coding (CABAC) has proven to be an efficient technique in the area of video coding. This paper presents an approach for integrating CABAC into the framework of frame-based animated mesh compression (FAMC). It presents the specific modifications and adaptations that have been worked out to adapt CABAC to the specific requirements of FAMC in order to build a...
