Robust Video Watermarking in Frequency Domain for Copyright Protection

Abstract

The problem of illegal video piracy can be overcome by the video watermarking method. Therefore, this paper presents a robust video watermarking technique for copyright protection based on redundant discrete wavelet transform (RDWT) and Schur transform. A grayscale watermark image is concealed into the 1-level LL sub-band of the video frame’s luminance channel (Y). The matrices, namely peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and normalized cross-correlation (NC) are used to assess the imperceptibility and robustness. The experimental results validate the performance of the proposed method.
