Demand for 3D content increased over the last years and more attention was dedicated to methods used in 3D content creation and transmission. View synthesis methods introduce localized artifacts when creating new virtual views. Evaluating these methods require therefore a different approach, in order to identify and emphasize synthesis artifact prone areas, while diminishing the impact, of other types...
The quality of side information plays a key role in distributed video coding. In this paper, we propose a new approach that consists of combining global and local motion compensation at the decoder side. The parameters of the global motion are estimated at the encoder using scale invariant feature transform features. Those estimated parameters are sent to the decoder in order to generate a globally...
In distributed video coding, the reference frames are used to generate a side information at the decoder in order to decode the Wyner-Ziv frame. The quality of side information has a strong impact on the coding efficiency of distributed video coding. The estimation of the side information becomes less accurate when the temporal distance between the neighboring reference frames increases or when the...
Three dimensional digital video services are gathering a lot of attention in recent years, thanks to the introduction of new and efficient acquisition and rendering devices. In particular, 3D video is often represented by a single view and a so called depth map, which gives information about the distance between the point of view and the objects. This representation can be extended to multiple views,...
In multi-view Distributed Video Coding, Side Information can be computed either from previously decoded frames in the same view, or from previously decoded frames in adjacent views. In this paper, we address the problem of effectively fusing these two predictions. For this purpose, we propose two Support Vector Machine based fusion algorithms. We also identify a number of features to be used in classification...
