With the development of 3D video technology, many studies have paid attention to compression efficiency and rate distortion performance. When 3D videos are transmitted over error-prone channels, they may suffer significant quality degradation. In this paper, we combine multiview video coding (MVC) with multiple description coding (MDC) for robust transmission. The proposed scheme can give full consideration...
High efficiency video coding (HEVC) is an emerging video compression standard, developed by the Joint Collaborative Team on Video Coding (JCT-VC). The aim of HEVC standardization effort is to save about 50% bit rate for equal perceptual video quality relative to H.264/AVC. Although HEVC provides greater bit rate saving, it also brings the enormous encoding complexity increase. In this paper, we propose...
Stereo video can bring people into more vivid and actual sense, but the video data is too huge to storage and transmit conveniently. In this paper, a compatible scheme which compresses stereo video with flexible prediction structure is proposed. In the proposed scheme, we define a group of picture (GOP) considering of the real time of the video. There are different prediction structures according...
Randomly selecting 8 × 8 host blocks in big-blocks for data embedding, YASS, a recently developed advanced stegano-graphic scheme makes these blocks not coincident with the 8×8 grids used in JPEG compression. As a result, it effectively invalidates the self-calibration technique used in modern steganaly-sis. However, the randomization is not sufficient enough, i.e., some positions in an image are...
H.264 is an advanced video compression standard and absorbs the advantages of the previous standard. In this paper, we propose a scheme which compresses the stereo video based on H.264 with adaptive prediction mode. In the proposed scheme, left sequence and right sequence are incorporated into one sequence firstly. Then the incorporated sequence is compressed with adaptive prediction mode. There is...
Multiple description coding (MDC) is a promising alternative for robust transmission of information over non-prioritized and unpredictable networks. Especially, MDC has emerged as an attractive approach for video applications where retransmission is unacceptable or infeasible. In this paper, an effective MD video codec is designed based on pre-and post-processing of video sequences, without any modification...
This paper introduces advanced channel codes turbo and LDPC to distributed video coding (DVC), and compares their performance in the whole system. From the simulation results, we can find that the LDPC codes are superior to turbo codes when the video sequence has high motion. Additionally, whether turbo or LDPC, the DVC system outperforms the conventional intra-frame coding though underperforms conventional...
