Abstract

ELBAşI, E.. Robust MPEG Watermarking in DWT Four Bands. J. appl. res. technol [online]. 2012, vol.10, n.2, pp.87-93. ISSN 2448-6736.

In this paper, we generalize an idea in a recent paper that embeds a binary pattern in the form of a binary image in the wavelet domain for images. Our generalization includes all four bands (LL, LH, HL and HH) in the DWT for MPEG video sequences. We tested the proposed algorithm against twelve attacks. Embedding the watermark in lower frequencies is robust to one group of attacks, and embedding the watermark in higher frequencies is robust to another group of attacks.

Keywords : non-blind video watermarking; DWT; visual watermark; MPEG; attacks.
