A comparative study on video watermarking capacity
Résumé
From both theoretical and applicative points of view, estimating with accuracy the video watermarking capacity is an ever challenging research topic. This paper completes the author's previous study and provides reference capacity values for a large variety of real life scenarios: the uncompressed and compressed (MPEG 4 AVC) video, the two most intensively used transforms in watermarking (DCT and DWT), different levels of robustness (from linear and non-linear filtering to geometrics attacks), and transparency (expressed by signal to noise ratios from 25 to 35 dB). The experiments are performed in industrial partnership, out of processing a heterogeneous video corpus of about 4 hours
