Content-aware layered compound video compression
Compound video compression is crucial for remote control and data assessment. In this paper, we propose a content-aware layered video coding scheme as an attempt to efficiently compress the compound video. In this scheme, the compound video is analyzed and processed progressively at three pyramid levels: block, object and layer. Firstly, the compound video is analyzed by a block type classification technique to access each block's spatial and temporal properties. Secondly, the natural video object is detected adaptively in each frame based on the block type. Finally, the compound video content is distributed into different layers and specifically designed video coding algorithms are employed to compress each layer. Experiments demonstrate that our proposed scheme can preserve the advantages of the employed compression algorithms for each layer and outperform each of them in the compound video compression.
