Optimal rate allocation is among the most challenging tasks to perform in the context of predictive video coding, because of the dependencies between frames induced by motion compensation. In this paper, using a recursive rate-distortion model that explicitly takes into account these dependencies, we approach the frame-level rate allocation as a convex optimization problem. This technique is integrated...
Optimal rate allocation is among the most challenging tasks to perform in the context of multi-view video coding, because of the dependency between frames induced by motion compensation and depth image-based rendering. In this paper, using a recursive rate-distortion model that explicitly takes into account these dependencies, we approach the frame-level rate allocation as a convex optimization problem...
As 3D media became more and more popular over the last years, new technologies are needed in the transmission, compression and creation of 3D content. One of the most commonly used techniques for aiding with the compression and creation of 3D content is known as view synthesis. The most effective class of view synthesis algorithms are using Depth-Image-Based-Rendering techniques, which use explicit...
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...
