Optimization of Bit Plane Combination for Efficient Digital Image Watermarking
In view of the frequent multimedia data transfer authentication and protection of images has gained importance in today’s world. In this paper we propose a new watermarking technique, based on bit plane, which enhances robustness and capacity of the watermark, as well as maintains transparency of the watermark and fidelity of the image. In the proposed technique, higher strength bit plane of di...
متن کاملRobust Digital Image Watermarking Algorithm against RST Attacks using Self-patch Correlation
In this paper, we propose an effective watermarking scheme using self-patch correlation based on Radon transform for image. The robustness against Rotation, Scaling, and Translation (RST) attacks is achieved using the translation property of the Radon transform and self-patch correlation. The Radon transform emphasizes and detects the linear characteristic to calculate the angle of image rotati...
متن کاملA Rectification Scheme for RST Invariant Image Watermarking
Rotation, Shifting, and Translation (RST) invariant image watermarking is a very important research topic. In this letter, we report a new filtering method in the log-polar mapping (LPM), and a novel rectification method that can be used in any RST invariant image watermarking algorithms. We get a log-polar mapping of an image by calculating the Fourier transform of the image and resampling the...

An Extended Dct Image Watermarking against Geometrical Attacks
Digital watermarking is an important technology in today’s world for protecting multimedia content from illegal copying of data. It is a process of concealing information. The main purpose of digital watermarking provided more robustness and integrity against geometrical attacks. In this paper, various digital watermarking techniques have been discussed and identified the best technique by comp...
