A motion-based side-information generation scheme with semi super-resolution for a scalable Wyner-Ziv coder framework is introduced. It is known that the performance of any Wyner-Ziv coder is heavily dependent on the efficiency of the side-information generation. We propose an iterative block based scheme to generate a semi super-resolution frame using the past and future reference frames which should be coded at full-resolution. To enable this side-information generation the framework should allow for low encoding complexity, reducing the spatial resolution only in the non-reference frames. The enhancement layer is produced using a residual frame of the reduced resolution encoded frame. The decoder first decodes the low resolution base layer and iteratively generates the side-information, along with channel decoding, to obtain a higher quality version of the decoded frame. Results of the implementation of the framework using the motion-based side-information in the H.263+ and H.264 standards are presented.

Wyner-Ziv video coding has become one of the hottest research topics in the video coding community due to the conceptual, theoretical and functional novelties it brings. Among the many practical architectures already available, feedback channel-based with channel coding, e.g. LDPC and turbo codes, solutions are rather popular. These solutions rely on decoder motion estimation based on periodic Intra coded key frames, setting the so-called GOP size, very much like in conventional video coding. This paper targets the rate-distortion and complexity performance study of this type of Wyner-Ziv coding solution as a function of the GOP size, considering both LPDC and turbo codes.

Wyner-Ziv coding, also known as distributed video coding, is currently a very hot research topic in video coding due to the new opportunities it opens. This paper applies the distributed video coding principles to stereo video coding, to propose a practical solution for Wyner-Ziv stereo coding based on mask-based fusion of temporal and spatial side informations. The architecture includes a low-complexity encoder and avoids any communication between the cameras/encoders. While the rate-distortion (RD) performance strongly depends on the motion-based frame interpolation (MBFI) and disparity-based frame estimation (DBFE) solutions, first results show that the proposed approach is promising and there are still issues to address.

Wyner-Ziv video coding with side matching for improved side information

2nd IEEE Pacific Rim Symposium on video and Technology

ISBN: (纸本)9783540771289

To make an encoder extremely simple by eliminating motion prediction/compensation from encoder, source coding with side information has been investigated based on the Wyner-Ziv theorem as the basic coding principle. However, the frame interpolation at decoder which is essential for redundancy elimination makes erroneous side information when the basic assumption of linear motion between frames is not satisfied. In this paper, we propose a new Wyner-Ziv video coding scheme featuring side matching in the frame interpolation to improve the side information. In the proposed scheme, Wyner-Ziv decoder compensates wrong blocks by side information using side matching and bi-directional searching. The noise reduction in side information allows the proposed algorithm to achieve coding improvements not only in bit-rate but also in PSNR. Results of our experiments show improvement of PSNR up to 0.40dB.

We investigate optimization of system performance in the below scenario: capturing and transmitting videos by single or multiple video sensors using distributed video coding (DVC) over ad hoe networks. There is an intrinsic contradiction in this scenario that could affect the system performance: the contradiction between the decoding quality and network lifetime. In this paper, we propose a joint optimization between the decoding quality and network lifetime using a quantitative metric of system performance, which is defined as the amount of collected visual information during the operational time of the video sensor. Based on the proposed metric, an optimal encoding rate is determined, which results in an optimal system performance. The simulation results show that the optimal encoding rate can be determined to achieve the optimal system performance.

distributed video coding (DVC) has become increasingly popular in recent times among the researchers in video coding due to its attractive and promising features. DVC primarily has a modified complexity balance between the encoder and decoder, in contrast to conventional video codecs. Side information generation, carried out at the decoder, is a major function in the DVC coding algorithm and plays a key-role in determining the performance of the codec. In this paper, a novel enhanced algorithm is proposed for the side information generation process where the side information is evolved over the processing of each bit plane. Simulation results of the proposed technique depict a consistent improvement in performance in comparison to the state-of-the-art in pixel domain DVC.

distributed video coding is a new video coding paradigim, with the ability to shift coding complexity from encoder to decoder. Turbo code based pixel-domain Wyner-Ziv codec is one of the most practical lossy DVC schemes. The performance of Wyner-Ziv codec significantly depends on the modeling of correlation noise statistics between the side information and the original Wyner-Ziv frames. It was observed that the correlation noise statistics differs temporally and spatially. In this paper, a novel algorithm is proposed to model the non-stationary col-relation noise statistics. The experiments show that the proposed algorithm has led to significant improvement for Wyner-Ziv coding performance.

Wyner-Ziv coding has been recognized as the most popular method up to now. For traditional WZC, side information is generated from intra-coded frames for use in the decoding of WZ frames. The unit for intra-coding is a frame and the distance between key-frames is kept constant. In this paper, the unit for intra-coding is a block, and the temporal distance between two consecutive key blocks can varying with time. A block is assigned a mode (WZ or intra-coded), depending on the result of spatio-temporal analysis, and encoded in an alternative manner. This strategy improves the overall coding efficiency, while maintaining a low encoder complexity. The performance gain can achieve up to 6 dB with respect to the traditional pixel-domain WZC.

distributed video coding (DVC) is an increasingly popular approach among the researchers in video coding during past few years due to its attractive and promismig features. In DVC, the majority of the computational complexity has been shifted from encoder to the decoder in comparison to its conventional counterparts, including MPEG and H.26x enabling a dramatically low cost encoder implementation. Side information generation, carried out at the decoder, is a major function in the DVC coding algorithm and plays a key-role in determining the performance of the codec. In this paper, a novel iterative refinement technique is proposed for the side information generation process. Simulation results of the proposed technique depict a consistent improvement in performance in comparison to the state-of-the-art in pixel domain DVC.

Conferenceon Visual Communications and Image Processing 2006

Some emerging applications may require flexible playback features for time-based media, such as video, that cannot be directly supported by current compression standards, because for these decoding of frames can only be done in a predetermined order. An example would be a video application where both backward and forward frame-by-frame playback are to be supported. A standard codec could support this by decoding complete GOPs in the desired order, and then playing back one frame at a time. Thus, potentially significant added delay and memory are needed to support backward playback, which can be lowered if small GOP sizes are chosen, at the cost of reduced coding efficiency. Other example applications where flexible playback may be desirable include switching between different views in multiview video coding, and accessing individual spectral bands in hyperspectral imagery. In this work we address flexible playback by showing that it becomes feasible when a particular data unit (e.g., a video frame) can be decoded using information from either one of a number of other data units (e. in the video case the next frame or the previous frame). Note that this is different from structures such as bi-directionally predicted frames, which require both predictor frames to be available at the decoder. We cast this problem as one of source coding with uncertainty about decoder side-information and propose a solution based on distributed source coding. In addition, we propose macroblock-based mode switching algorithms in the context of distributed video coding to improve coding efficiency. Our results show that, using forward/backward playback as an example, our proposed solution can achieve good coding efficiency without incurring additional delay and memory overhead.
