Colour image watermarking in real life
نویسنده
چکیده
In this report we present our work for colour image watermarking in different domains. First we consider mobile applications of watermarking and their properties. We implement a watermark into multimedia message and extract it. Using a set of observers we study image quality changes. Interesting results were found for human vision sensitivity to image type. Then we extend watermarking techniques from conventional to spectral images. We utilize wavelet domain for watermark embedding and apply different compression ratios and various illuminators to see how they effect to quality of the image and extracted watermark.

Hardware Implementation of Genetic Algorithm Based Digital Colour Image Watermarking
The objective of this work is to develop a hardware-based watermarking system to identify the device using which the photograph was taken. The watermark chip will be fit in any electronic component that acquires the images, which are then watermarked in real time while capturing along with separate key. Watermarking is the process of embedding the watermark, in which a watermark is inserted in ...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

Introduction: Digital cameras are the most popular image acquisition device. Images taken with a digital camera are usually downloaded on a personal computer (PC) where they are watermarked [1] for copyright protection and ownership authentication prior to storage and re-distribution. However, this way provides a space that attackers can utilise to violate intellectual property and ownership ri...

متن کاملProposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
