An improved rate-distortion model is developed to compare the performances of different multiview video coding (MVC) schemes. We first formulate the coding efficiency of one frame with a given temporal and inter-view prediction configuration. The overall performance of a MVC scheme is then obtained by averaging the coding efficiencies of all frames in all views, with different prediction configurations...
Albeit multiple description coding is a hot topic in compressed image/video transmission, there has not been extensive research on MDC for multiview data. In this paper, a multiview image multiple description coding scheme is proposed by combining rectification based view interpolation and encoding prediction residue. The joint optimal bit allocation of several components in our system is also discussed...
Current view synthesis prediction (VSP) techniques for multiview video coding (MVC) rely on disparity-based view interpolation or depth-based 3D warping. The former cannot be applied to every camera view, whereas the latter may require coding of the depth information of a scene. To avoid these constraints, we propose an improved VSP-based MVC scheme based on the following three techniques: 1) view...
View interpolation has been applied in multiview view coding. However, existing schemes assume all cameras are aligned. These methods may not perform well when neighboring cameras point to different directions. In this paper, we apply the rectification based view interpolation to MVC. We first derive the theoretical performance gain of the rectification based view interpolation over existing interpolation...
A projective rectification-based view interpolation algorithm is developed for multiview video coding and free viewpoint video. It first calculates the fundamental matrix between two views without using any camera parameter. The two views are then resampled to have horizontal and matched epipolar lines. One-dimensional disparity is estimated next, which is used to interpolate the image for an intermediate...
A hybrid error concealment method for H.264 compressed video is presented in this paper. The method can adequately exploit the spatial and temporal relativities of video sequence to adaptively select the spatial concealment or temporal concealment according to the boundary match criterion. In order to further improve the reconstructed video quality, a maximum a posteriori (MAP) estimator is then employed...
