In this paper, the transmission distortion introduced in the coded multi-view video stream is analyzed by mathematical method. This model takes into account the interdependent coding among views, which is an important component of multi-view video coding. The model can be used for any multi-view video coding scheme that uses motion compensation and disparity compensation, transform coding and entropy...
This paper analyzes the distortion in decoded multi-view video caused by random packet losses in the underlying transmission network and proposes an error concealment method for for multi-view video. Taking into account the interdependent coding among views, which is an important component of multi-view video coding, a distortion estimation formula is developed by mathematical discursion. Additionally,...
In the draft of multi-view coding (MVC), variable size motion estimation and disparity estimation are employed to select the best coding mode for each macroblock. These techniques achieve the highest possible coding efficiency, but they result in extremely large computation complexity which obstructs MVC from practical application. This paper proposes a fast mode size decision algorithm for MVC in...
A new MVC structure is proposed for stereo video compression.Coding performance of the MVC structures is evaluated by DPSNR (disparity peak signal-to-noise ratio) of five well-designed stereo video experiments. The experiments' results show that the classification performance, compared with the reference MVC structure, is improved in the new-designed coding structures .It is also proved by the rate-distortion...
In this paper, a real-time high-resolution multi-view video transport system which can deliver multi-view video over IP networks is proposed. Video streams are encoded with H.264/AVS. Owing to the massive amount of data involved, multi-view video is delivered in two separate IP channels. Since packets losses always occur in IP networks, a novel packets processing method is employed in the proposed...
The fundamental problem associating error resilience with vision-related technique is how to generate a plausible substitute for the unknown regions with complex and semantic structure, implicitly or explicitly by adding significant context redundancy to the coded video, subject to local similarity and global consistence in tempo-spatial domain. Following the structure-aware inpainting for image coding,...
Still stereoscopic pictures compression is an important part of auto-stereoscopic techniques. H.264 is an advanced video compression standard, absorbing the advantages of the previous standards. In this paper, still stereoscopic pictures compression is studied, and H.264 coding tools adopted to achieve this compression are discussed. The still stereoscopic pictures compression schemes based on H.264,...
This paper provides a scheme for MFEG-2 to H.264 transcoding. This scheme is composed of two parts: intra prediction and inter prediction. For the intra prediction part, 8 times 8 block DCT-HT transform-domain converse is used, and then intra mode decision is done in HT domain to obtain the optimum mode, so that good intra prediction is acquired. For the inter prediction part, motion vector (MV) got...
This paper researches about an intelligent surveillance system, which is used for surveiling separated-moved and important remote-object. This system is based on WLAN, which followed the IEEE 802.11b/g and could communicate smoothly with Ethernet or Internet etc. For an intelligent video encoder, we used an efficient video coding algorithm based on SPIHT (set partition in hierarchical trees), which...
