Reversible Image Watermarking Based on Histogram Modification
In this paper, a new reversible watermarking scheme resistant to geometrical attacks is presented. The proposed scheme does not need the original image for extracting the watermark, and induces not noticeable distortion during the watermarking procedure. The embedding algorithm has low computational complexity, can be applied to very small images (down to 16 x 16), and provides capabilities of ...
متن کاملCropping Resilient Watermarking Based on Histogram Modification
This paper proposes a watermarking scheme robust against most common geometric and signal processing operations, for applications that require an accurate detection of the owner watermark even if the digital image suffers intentional and non-intentional attacks. The proposed scheme is based on two modifications introduced in two 2D histograms. In the first modification a selected region of a 2D...
متن کاملHigh Payload Lossless Digital Image Watermarking Using Integer Wavelet Transform
In this paper a high payload lossless digital image watermarking technique based on Integer Wavelet Transform is proposed. Digital watermarking is the process of embedding the watermark image into a host image which is imperceptible by human visual system. The small deviations in data values are not allowed in certain images for obvious reasons and a potential risk of a person misinterpreting a...
متن کاملWatermarking Based on the Hyperanalytic Wavelet Transform
In this paper we present a new technique for watermarking in the hyperanalytic wavelet domain. This has the advantage of better directional selectivity and shift invariance compared to the classical wavelet filter. The watermark is inserted into all levels of decomposition using a perceptual mask conceived by the authors. We compare this technique with two systems in the DWT domain, and show it...
متن کاملBiorthogonal Wavelet Transform Digital Image Watermarking
With the growing popularity of Digital Medias through the World Wide Web, intellectual property needs copyright protection, prevention of illegal copying and verification of content integrity. The new data hiding techniques need to be developed that satisfy the requirements of Imperceptibility, Robustness, Capacity, or data hiding rate and Security of the hidden data etc. Watermarking has been ...
