Distributed Monoview and Multiview Video Coding

Abstract

A growing percentage of the world population now uses image and video coding technologies on a regular basis. These technologies are behind the success and quick deployment of services and products such as digital pictures, digital television, DVDs, and Internet video communications. Today's digital video coding paradigm represented by the ITU-T and MPEG standards mainly relies on a hybrid of blockbased transform and interframe predictive coding approaches. In this coding framework, the encoder architecture has the task to exploit both the temporal and spatial redundancies present in the video sequence, which is a rather complex exercise. As a consequence, all standard video encoders have a much higher computational complexity than the decoder (typically five to ten times more complex), mainly due to the temporal correlation exploitation tools, notably the motion estimation process. This type of architecture is well-suited for applications where the video is encoded once and decoded many times, i.e., one-to-many topologies, such as broadcasting or video-on-demand, where the cost of the decoder is more critical than the cost of the encoder.Distributed source coding (DSC) has emerged as an enabling technology for sensor networks. It refers to the compression of correlated signals captured by

Interactive Streaming of Stored Multiview Video Using Redundant Frame Structures

“…In addition, DSC has been investigated for a variety of applications, ranging from scalable coding [33], [34], error resilience video transmission [35], [36], distributed compression of multiview image/video [37], [38], to hyperspectral image compression [39] (see [40] for a recent survey). In this paper, we extend our previous work [10], [11] to apply DSC to facilitate interactive view switching, and this is significantly different from other DSC applications.…”

Side information estimation and new symmetric schemes for multi-view distributed video coding

“…That is why we have to give a particular attention to these interpolation methods. In our codec we use the estimator proposed by Ascenso et al in [4,[16][17][18], shown in Fig. 5.…”

A New Scheme of Distributed Video Coding Based on Compressive Sensing and Intra-Predictive Coding

“…DVC has been proposed to reduce the complexity in video encoding [1], [4]. Successive frames of a video sequence are encoded independently at the encoder, while they are subjected to a joint decoding at the decoder with a help of correlation among neighboring frames.…”

“…Distributed video coding (DVC) is advantageous for making a low-complexity/low-power encoder, since complex tasks such as motion estimation and motion compensation (ME/MC) can be shifted away from an encoder to a decoder [1]- [4]. Instead, a DVC decoder is powered by distributed decoding that uses the temporal/spatial correlation available from side information.…”
