Conventional color image watermarking usually causes sever color and texture distortions when applied to high dynamic range images. In this paper, we thus propose a new color image watermarking method for high dynamic range image. Based on modification of the blue component in the detail layer of host image, some color and texture distortions can be significantly reduced. Set of experiments are carried out to verify our concept. The experimental results show an efficiency of the proposed method, in both higher quality of watermarked image and more robustness of embedded watermark against various types of attack, compared to the previous work .
