Reversible data embedding theory has marked a new epoch for data hiding and information security. Being reversible, the original data and the embedded data should be completely restored. Difference expansion transform is a remarkable breakthrough in reversible data-hiding schemes. The difference expansion method achieves high embedding capacity and keeps(More)
—In this paper, we propose a hybrid approach for accurate depth acquisition by using a structured light-based method with a stereo matching. By projecting additional light patterns onto a scene, a structured light-based method works well on a textureless region where a stereo matching shows poor performance. In contrast, the patterns projected onto a rich(More)
This paper presents ISO/IEC 23000-5 -media streaming player, an ISO standard targeting the distribution of governed content in streaming mode. This standard is a major integration of MPEG technologies, ranging from MPEG-2 and MPEG-4 to MPEG-21 including a set of inter-device protocols developed by the Digital Media Project, now ISO/IEC 29116-1 -Media(More)
This paper describes experimental demonstration of holographic 3D reconstructions with a directly-viewing, transmissive, amplitude-modulating 5.5" LCD SLM device in monochrome. A full-complex field modulation is achieved by the single amplitude-modulation SLM module using the Burckhardt-encoding scheme at the cost of the decrease in sampling. We define an(More)
We demonstrate a tabletop holographic display system for simultaneously serving continuous parallax 3.2-inch 360-degree three-dimensional holographic image content to multiple observers at a 45-degree oblique viewing circumference. To achieve this, localized viewing windows are to be seamlessly generated on the 360-degree viewing circumference. In the(More)
