Abstract: A Study on Color-Texture Image Watermarking Based on Texture Analysis
Nowadays, texture images have been presented and used in a great deal of industry and life application and copyright protection of texture images has become urgent problem. With this reason, we propose a color-texture image watermarking algorithm utilizing texture properties. The proposed algorithm selects suitable blocks to embed a watermark by using energy and homogeneity properties of grey l...
متن کاملTexture-based watermarking of 3D video objects
In this article, we describe a novel framework for watermarking 3D video objects via their texture information. Unlike classical algorithms dealing with 3D objects that operate on meshes in order to protect the object itself, the main goal of our work is to retrieve information originally hidden in the texture image of the object, from resulting images or videos having used the 3D synthetic obj...
متن کاملHigh Capacity Watermarking in Nonedge Texture Under Statistical Distortion Constraint
High-capacity image watermarking scheme aims at maximize bit rate of hiding information, neither eliciting perceptible image distortion nor facilitating special watermark attack. Texture, in preattentive vision, delivers itself by concise high-order statistics, and holds high capacity for watermark. However, traditional distortion constraint, e.g. just-noticeable-distortion (JND), cannot evalua...
متن کاملAnalysis of information behavior paradigms: past and present
Introduction: Information behavior in knowledge and information science is seen as a fundamental human behavior that has been studied extensively thus far. This study include different approaches and perspectives that examined information behavior. The purpose of this article is to investigate the paradigm shift in information behavior by using the texts of this research ground. Methodology: Th...
متن کاملDigital Watermarking Using Local Contrast-based Texture Masking
Digital image watermarking algorithms embed identifying marks that can be used for authentication. To make the distortions induced by the embedding process imperceptible, the watermarking algorithm must determine their visual threshold. This paper presents: (1) the results of a psychophysical detection experiment for wavelet-distortion targets presented against textured backgrounds of varying c...
