H264SVC-wm Source Code

This is "The Multimedia Signal Processing and Security Lab", short WaveLab, website. We are a research group at the Computer Sciences Department of the University of Salzburg headed by Andreas Uhl. The short name "WaveLab" already indicates that wavelets are among our favorite tools - we have 15 years of experience in this area. Our research is focused on Multimedia Security including Watermarking, Image and Video Compression, Medical Image Classification, and Biometrics.

Abstract: In this paper we investigate robust watermarking integrated with H.264/SVC video coding and address coarse-grain quality and spatial resolution scalability features according to Annex G of the H.264 standard. We show that watermark embedding in the base layer of the video is insufficient to protect the decoded video content when enhancements layers are employed. The problem is mitigated by a propagation technique of the base layer watermark signal when encoding the enhancement layer. In case of spatial resolution scalability, the base layer watermark signal is upsampled to match the resolution of the enhancement layer data. We demonstrate blind watermark detection in the full- and low-resolution decoded video for the same adapted H.264/SVC bitstream and, surprisingly, can report bit rate savings when extending the base layer watermark to the enhancement layer.
