High Dynamic Range (HDR) images have been widely applied in daily applications. However, HDR image is special format, which need to pre-process known as tone mapping operators for display. Since the visual quality of HDR images are very sensitive to luminance value variations, conventional watermarking methods for low dynamic range (LDR) images are not suitable and may even cause catastrophic visible distortion. Currently, few methods for HDR image watermarking are discussed. In this paper, we propose a watermarking scheme for HDR image. Both of the subjective and objective qualities of watermarked image are improved. What's more, it also shows higher robustness against tone mapping operations.
