Abstract

Digital watermarking can be used to ensure the authenticity and copyright protection of images. In watermarking balancing the trade-offs between its features is an important issue. To address this issue, in this work an adaptive hybrid domain color image watermarking based on Discrete Wavelet Transform (DWT), Walsh Hadamard Transform (WHT), and Singular Value Decomposition (SVD) is proposed. Here, watermarking is carried on YCbCr color space. In this work, the embedding factor is calculated adaptively using the visual entropy and edge entropy. For better robustness the watermark is inserted into the Y component of YCbCr color Space. Further, Arnold Transform (AT) is used to secure the watermark. The average PSNR and SSIM of the proposed hybrid domain adaptive watermarking scheme is 40.0876 dB and 0.9883 respectively. The experimental results compared to the recent hybrid domain color watermarking, illustrate the superiority of the suggested approach.
