Abstract

Abstract

Some existing color image adaptive watermarking algorithms do not fully utilize the color information in the adaptive process, or do not consider the holistic property of the components of a color host image. To overcome these drawbacks, this paper proposes a color image adaptive watermarking algorithm based on Fractional Quaternion Fourier Transform (FrQFT). Firstly, the texture, edge and color tone features of the blocks of the host image are extracted using the Human Vision System (HVS). After that, the embedding strength values of the blocks suitable to watermark embedding are set adaptively according to the extracted feature. Finally, the quantization index modulation and the multiple redundant embedding strategy are used to insert the watermark in the FrQFT domain with the adaptive strength. Experimental results show that the proposed algorithm is superior over the existing algorithm using Quaternion Fourier Transform (QFT) and the algorithm based on Fractional Fourier Transform (FrFT).
