“…Visually imperceptible watermarking methods have been previously proposed for SDR content, e.g., [17], [18], and just recently for HDR images [19]. Differently from the watermarking method in [19], HDR-IVW-V avoids watermarking every single frame by segmenting the video into scenes composed of perceptually similar frames.…”

“…In this way, a novel watermarking algorithm named invisible-visible watermarking has been proposed as digital representation of the watermarks in real-world applications; in this algorithm, the imperceptibility, payload, and robustness of the invisible and the visible watermarking algorithms are combined with the high quality, resolution [13,14], and the robust display processing capabilities [14][15][16][17] incorporated into several electronic devices. This new watermarking technology can be classified by its exhibition stage as unseen-visible watermarking (UVW) [18][19][20][21] and imperceptible-visible watermarking (IVW) [22][23][24][25], as shown in Figure 1. The UVW algorithms [18][19][20][21] embed imperceptibly a watermark pattern through a visible watermarking strategy and take advantage of the image enhancement functions provided by the display devices, such as brightness, contrast, gamma, etc.…”

Imperceptible–Visible Watermarking to Information Security Tasks in Color Imaging

Digital image watermarking algorithms have been designed for intellectual property, copyright protection, medical data management, and other related fields; furthermore, in real-world applications such as official documents, banknotes, etc., they are used to deliver additional information about the documents’ authenticity. In this context, the imperceptible–visible watermarking (IVW) algorithm has been designed as a digital reproduction of the real-world watermarks. This paper presents a new improved IVW algorithm for copyright protection that can deliver additional information to the image content. The proposed algorithm is divided into two stages: in the embedding stage, a human visual system-based strategy is used to embed an owner logotype or a 2D quick response (QR) code as a watermark into a color image, maintaining a high watermark imperceptibility and low image-quality degradation. In the exhibition, a new histogram binarization function approach is introduced to exhibit any watermark with enough quality to be recognized or decoded by any application, which is focused on reading QR codes. The experimental results show that the proposed algorithm can embed one or more watermark patterns, maintaining the high imperceptibility and visual quality of the embedded and the exhibited watermark. The performance evaluation shows that the method overcomes several drawbacks reported in previous algorithms, including geometric and image processing attacks such as JPEG and JPEG2000.

“…Our method, hereinafter called High Dynamic Range -Imperceptible Watermarking, (HDR-IW) provides an easy way to recognize the media's ownership without the need for exchanging keys or any extra information about the embedding process, while minimizing the visual distortion that can be perceived by the HVS. The proposed method is based on the Unseen Visible Watermarking (UVW) technique [2], [3] and extends our work in [4]. Differently from the UVW technique, which embeds copyright information in the spatial domain of SDR regions with low visibility, the HDR-IW method embeds imperceptible watermarks in the spatial domain by exploiting the inaccuracies among the nonlinear digital representation of the linear luminance acquired by an HDR sensor, the linear luminance radiated by an HDR screen by means of a TF, and the brightness perceived by the HVS from the displayed luminance.…”

Watermarking of HDR Images in the Spatial Domain With HVS-Imperceptibility

2020

View full text Add to dashboard Cite

This paper presents a watermarking method in the spatial domain with HVS-imperceptibility for High Dynamic Range (HDR) images. The proposed method combines the content readability afforded by invisible watermarking with the visual ownership identification afforded by visible watermarking. The HVS-imperceptibility is guaranteed thanks to a Luma Variation Tolerance (LVT) curve, which is associated with the transfer function (TF) used for HDR encoding and provides the information needed to embed an imperceptible watermark in the spatial domain. The LVT curve is based on the inaccuracies between the non-linear digital representation of the linear luminance acquired by an HDR sensor and the brightness perceived by the Human Visual System (HVS) from the linear luminance displayed on an HDR screen. The embedded watermarks remain imperceptible to the HVS as long as the TF is not altered or the normal calibration and colorimetry conditions of the HDR screen remain unchanged. Extensive qualitative and quantitative evaluations on several HDR images encoded by two widely-used TFs confirm the strong HVSimperceptibility capabilities of the method, as well as the robustness of the embedded watermarks to tone mapping, lossy compression, and common signal processing operations. INDEX TERMS HDR, invisible watermarking, visible watermarking, LVT curve, HVS-imperceptibility.
