Abstract

In this work, we describe an approach that moves from the concept of spatial MDC and improves coding efficiency by exploiting some form of scalability. In the algorithm, we first generate four subsequences by sub-sampling, these subsequences are then taken in pairs that will form each of the two descriptions. For each description, one of the original subsequences is predicted from the other one via some scalable algorithms, focusing on the inter layer prediction scheme. The proposed algorithm has been implemented as pre- and post- processing of the standard H.264/SVC coder. The experimental results presented show that the algorithm provides excellent results in several conditions including 3D video sequence
