High-dynamic range (HDR) images are circulated rapidly over the internet withrisks of being exploited for unauthorized usage. To protect these images, someHDR image based watermarking (HDR-IW) methods were put forward. However, theyinherited the same problem faced by conventional IW methods for standarddynamic range (SDR) images, where only trade-offs among conflictingrequirements are managed instead of simultaneous improvement. In this paper, anovel saliency (eye-catching object) detection based trade-off independentHDR-IW is proposed, to simultaneously improve robustness, imperceptibility andpayload. First, the host image goes through our proposed salient objectdetection model to produce a saliency map, which is, in turn, exploited tosegment the foreground and background of the host image. Next, the binarywatermark is partitioned into the foregrounds and backgrounds using the samemask and scrambled using a random permutation algorithm. Finally, the watermarksegments are embedded into selected bit-plane of the corresponding hostsegments using quantized indexed modulation. Experimental results suggest thatthe proposed work outperforms state-of-the-art methods in terms of improvingthe conflicting requirements.
