Abstract— There arefew watermarking algorithms for color images. In most traditional watermarking algorithms, transforms are applied to each component of the color model individually resulting in less robust experimental results. Therefore, we propose a color image watermarking algorithm which is a high-dimensional algorithm. First, Octonion Discrete Cosine Transform (ODCT) and its inverter transform (IODCT) are proven. Then, a novel color image watermarking technique based on ODCT is proposed. Experimental results show that it not only has good antito compression ability, but also has robustness to noise, filtering and rotation attacks.

Index Terms—Octonion, discrete cosine transform, color image watermarking.
