High-Efficiency Video Coding (HEVC) is the newest video coding standard and presents improved efficiency. However, the coding computational complexity of this process is significant because of its coding structure called quad-tree structure coding units (CUs) for improving compression efficiency. In this paper, a fast algorithm based on image complexity of current CU is proposed to reduce the computational...
This paper presents a novel compression algorithm to replace Depth Modeling Mode for coding the depth-map. The result demonstrates that the execution time is reduced on an average 54.7% while the BD-rate of virtual views increase only 1.47%.
In this paper, a novel scheme of two-stage multiview image compression is proposed to create two-level reconstructed quality. Differently from the conventional multiview image compression algorithms, SIFT (Scale-Invariant Feature Transform) features matching from interview images are exploited to remove the correlations between multiple views. In the first stage coding, SIFT and RANSAC (RANdom SAmple...
The Shannon/Nyquist sampling theorem claim that when capturing a signal, one must sample at least two times faster than the signal bandwidth in order to avoid losing information. Nowadays, compressive sensing, as a big idea in signal processing, is a new method to capture and represent compressible signals at a rate significantly below the Nyquist rate. In this paper, compressive sensing is applied...
Multiple description coding (MDC) has emerged as an attractive approach for video applications where retransmission is unacceptable or infeasible. Considering that in a video sequence not one but many scene are joined together, we make the coder work on when scene are changing, and some methods are designed for this condition. The experimental results exhibit better performance of the proposed scheme...
Multiple description coding is especially promising for video coding due to the very stringent delay requirement in many video applications. In this paper, an effective MD video codec is designed based on motion-compensated correlation of video sequences, which is perfectly compatible with the current standard source or channel codec. The experimental results exhibit better performance of the proposed...
Joint source-channel decoding (JSCD) techniques have been proposed to reduce symbol error rate and bit error rate in decoding a sequence through exploiting the residual redundancy, but these techniques always employ only spatial residual redundancy. In this paper, a new JSCD scheme which exploits both spatial and temporal redundancy in motion vector data (MVD) is proposed. Simulation results show...
