Comparison between the classical nonblind video multiple watermarking system (grayscale image watermark) and the proposed method where (a) and (b) show original video frame and original watermark, (c) and (d) show watermarked video frame and recovered watermark without interlacing, (e) and (f) show watermarked video frame and recovered watermark with one-level interlacing, and (g) and (h) show watermarked video frame and recovered watermark with two-level interlacing.
