Spatially scalable video coding (SSVC in short) provides an efficient way to deliver one video at different resolutions. Based on the development of emerging High Efficiency Video Coding (HEVC), we propose a SSVC scheme to provide both single-loop and multi-loop solutions by enabling different inter-layer prediction mechanisms. Specifically, there are three basic inter-layer prediction modes, inter-layer...
This paper proposes an advanced spatially scalable video coding approach that exploits the inter layer correlation between different resolution layers by classified patch learning. The novelty of our proposed scheme is twofold. First, the correlation between low and high resolution frames is explored at patch level with regard to image features. Patches extracted from the previous coded frame are...
We present a new error concealment algorithm for spatially scalable video coding with frame loss in the enhancement layer, based on the technique of hallucination. For a lost enhancement layer frame, the error concealment is done as hallucinating its base layer frame, using the database trained from previously decoded frames nearby to the lost one. Simulation results show that the proposed method...
In existing pyramid-based spatially scalable coding schemes, such as H.264/MPEG-4 SVC (scalable video coding), video frame at a certain high-resolution layer is mainly predicted either from the same frame at the next lower resolution layer, or from the temporal neighboring frames within the same resolution layer. But these schemes fail to exploit both kinds of correlation simultaneously and therefore...
