| contents | A Chaos-Based Video watermarking in Wavelet Domain Somayyeh Mohammadi Estudios Ambientales security robustness Chaotic maps wavelet transform video watermarking A novel vide o watermarking scheme based on chaotic maps and wavelet transform is proposed in this paper. The algorithm encrypts a logo image as a watermark signal by bit xor’ing the pixel values of logo and a chaotic map, thus the security of the proposed scheme will be increased . In order to enjoy a robust watermarking algorithm, the chaotic watermark signal is embedded into the discrete wavelet transform coefficients of I - frames,. The investigational results demonstrate that the proposed design can achieve outstandin g robustness to common attacks, and it surpasses the existing techniques. 2015 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467547683048 en http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.6-2 Vol.37 |
