An Approach to Embed Image in Video as Digital Watermark
Nagajyothi. T , Dr. Amit Kr. Jain
Digital watermarking covers the secret or personal data in digital images to guard their copyrights. Currently, copyright protection of digital contents, lack of authentication and ownership proof has become a critical issue due to internet growth. To overcome these issues a blind invisible dual video watermarking approach is proposed in this work. Both second level and third level DWT(Discrete Wavelet Transform) are processed in this work. By second level a watermark image (one image embedded over another image) is acquired. The watermark image is then embedded into the third level DWT to provide high level watermarked video. This embedding process is done with only the luminance component of video. Since invisible watermarking approach is utilized the watermark image is given in an invisible form. Consequently, after embedding process extraction process takes place. Thus the watermark image is sent in a secure manner preventing unauthorized usage and copyright issues. The execution time of embedding process and extraction process, Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) and Normalized Correlation Coefficient (NCC) is inspected.
