We propose a new coding technology for 3D video represented by multiple views and the respective depth maps. The proposed technology is demonstrated as an extension of the recently developed high efficiency video coding (HEVC). One base views are compressed into a standard bitstream (like in HEVC). The remaining views and the depth maps are compressed using(More)
This documents presents an approach of providing multiview compression capability in HEVC in similar way to MPEG-4 AVC/H.264 Annex H. The results for experimental implementation of HEVC-based multiview codec and prospective performance of multiview prediction in HEVC-based multiview codecs are described. Codec has been implemented using HEVC reference(More)
—During the last two decades, a new technology generation of video compression was introduced about each 9 years. Each new compression-technology generation provides halving of necessary bitrates as compared to the last previous generation. This increasing single-view compression performance is related to increasing compression performance of multiview(More)
In this paper, we present the most efficient coding tools that are used in a new video compression technology for multiple views with the depth maps. This very well performing technology was designed and developed in response to MPEG Call for Proposals on 3D Video Coding Technology. The proposed technology exploits a tool that reduces the side views and the(More)
— The paper describes watermarking of compressed video bitstreams. This technique is proven to be very fast and robust against various attacks including camcorder recording attack. The watermark is embedded using indirect modifications of transform coefficients in selected P-and B-frames. In the watermarked bitstream there exist sequences of watermarked(More)
The paper deals with multiview video coding using the new technology of High Efficiency Video Coding (HEVC). Implementation of multiview video coding in the framework of HEVC is described together with new specific tools proposed by the authors. Extensive experimental results are reported for compression performance comparison of MVC (ISO 14496-10), HEVC(More)
— A computationally inexpensive watermark schema for MPEG-4 AVC/H.264 streams that use local mark strength adjustment minimizing visible artifacts is presented. The local mark strength adjustment mechanism and watermark embedding mechanism operate on residual data. This approach minimize the number of operations needed for video bitstream decoding and(More)
In this paper, we present the original compression technology that was designed and developed at Poznań University of Technology in response to MPEG Call for Proposals on 3D Video Coding Technology. One view is coded in the HEVC syntax while the side views and the depth maps are very efficiently coded exploiting various redundancies that are related to(More)
This paper reviews the results of dielectric studies of the proton glass state in a mixed crystal Rubidium Ammonium Dihydrogen Arsenate (RADA) The coexistence of paraelectric/proton glass and ferroelectric or antiferroelec-tric orders, confirmed by other studies, has been discussed in detail. The phase diagram of RADA is asymmetric. The proton glass state(More)
