Digital watermarking of still images in the presence of de-synchronization attacks: theoretical analysis and development of practical algorithms WP2: Development of practical algorithms

چکیده
The perceptual impact of the geometric distortions introduced by the multiresolution version of the C-LPCD model is evaluated by means of psychovisual experiments. Specifically, the maximum admissible distortion that can be applied before the distortion becomes visible is measured leading to the definition of the perceptually admissible subset of C-LPCD distortions. A similar analysis is performed with regard to the MRF model.

متن کاملIncreasing the Capacity and PSNR in Blind Watermarking Resist Against Cropping Attacks
Watermarking has increased dramatically in recent years in the Internet and digital media. Watermarking is one of the powerful tools to protect copyright. Local image features have been widely used in watermarking techniques based on feature points. In various papers, the invariance feature has been used to obtain the robustness against attacks. The purpose of this research was based on local f...
متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
متن کاملStochastic Image Warping for Improved Watermark Desynchronization
The use of digital watermarking in real applications is impeded by the weakness of current available algorithms against signal processing manipulations leading to the de-synchronization of the watermark embedder and detector. For this reason, the problem of watermarking under geometric attacks has received considerable attention throughout recent years. Despite their importance, only few classe...
متن کاملA survey on digital data hiding schemes: principals, algorithms, and applications
This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...
