Abstract:

In this paper we concentrated on the transform domain watermarking wherein we took video as a cover medium and some binary images as watermark to be embedded behind the video. In this proposed method we combined two of the most important and useful transformations, namely Discrete Wavelet Transform and Discrete Cosine Transform, for the purpose of digital watermarking. We evaluated the proposed method with some visual quality matrices.
