A Video Watermarking Scheme Resistant to Geometric Transformations

Abstract

This paper describes a blind video watermarking system invariant to geometrical attacks. Our scheme embeds different parts of a single watermark into different shots of a video under the wavelet domain. A multi resolution motion estimation algorithm (MRME) is adopted to preferentially allocate the watermark to coefficients containing motion. In addition, embedding and extraction of the watermark are based on the relationship between a coefficient and its neighbors. Experimental results show that inserting watermark where picture content is moving is less perceptible. Further, it shows that the proposed scheme is robust against common video processing attacks.
