Imperceptible Visible Watermarking with Watermark Readability Improved

In recent years, most digital capture devices have been designed with several post capture processing functions such as histogram modulation, based on this an Imperceptible-Visible Watermarking (IVW) scheme has been proposed to deliver auxiliary information and claim the ownership of digital images. In this paper an improved versin of imperceptible-visible watermarking is introduced, where the just noticeable distortion (JND) is used in the embedding stage to improve the watermark readability through a novel histogram binarization function in the exhibition stage. The experimental results show that the proposed strategies can improve the performance of several IVW schemes in the context of watermark imperceptibility and readability, which are similar with the most recent IVW schemes reported until now. The benchmarking performance of the proposed strategies is done through of the Peak Signal to Noise Ratio, Structural Similarity Index Measure, and the Bit Error Rate.
