We propose a novel technique for coding of texture and three-dimensional data which takes the viewer position into account. This allows to transmit only the most visible parts of information that is needed to render a virtual scene. The rendering operation is modelled and studied using filtering and sampling theory. The technique is applied on real data and(More)
This deliverable details the application scenarios for which DVC may bring major benefits, highlighting the expected advantages for each scenario. In particular, the functionalities usually identified in the literature as DVC strengths, such as error resilience, encoder-decoder complexity trade-off, low-power encoder consumption, but also coding efficiency(More)
In order to satisfy the needs of new applications in a multimedia environment the problem of object-oriented coding has to be addressed. In this paper two main approaches are presented to tackle this problem. First, an algorithm for shape coding is presented. It, is based on a chain coding algorithm where powerful modeling techniques are used to increase(More)
Semantic segmentation is generally associated with second generation video coders, or object-based coders. Object-based coders encode different video objects separately in order to achieve lower bitrates and to enable object-based functionalities. In this paper, we present an encoding framework that uses semantic segmentation to improve the performance of(More)
