Abstract

Video watermarking is well known as the process of embedding copyright information in video bit streams. It has been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video. In this study, the algorithm is based on cascade of two powerful mathematical transforms; Dual Tree Complex Wavelet Transform (DTCWT) and Singular Value Decomposition (SVD). RGB frames of the video is converted into YCbCr frames. For embedding, Y channel (luminance) is selected, then two dimensional Dual Tree Complex Wavelet Transform (DT-CWT) is applied on and then Singular Value Decomposition is applied on it. The same is performed on the watermark to be added. Then by convolving the host image and watermark image, watermarked signal is produced. Different quality metrics are also used, in order to determine the efficiency of the system retaining the watermark.
