Comparitive Analysis of Watermarking in Digital Images Using 3- Level DWT & LBP
نویسندگان
چکیده
Digital watermarking has rise as a new research area for preventing illicit copying and duplication. In this paper two methods 3-level DWT & Local Binary Pattern (LBP) algorithm for watermarking in digital images are discussed. In order to compare the robustness of both algorithms noise attack is used.

A Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...

متن کاملOptimized Perceptual Quality, Robust and Highly Secured Randomly Scrambled Image Watermarking using 3-Level DWT Domain
In networks the content distribution through genuine channels needs the use of digital watermarks. The digital watermark is to make the content self-identifying i.e. to place the information within the content itself. Digital images are the significant vector for network communication. As 2D-image signals are non-stationary signal wavelet transform is more suitable to analyze this signal. This ...

The growth of the Internet has frequently increased the availability of digital data such as text, audio, images and videos to the public. Digital watermarking is one of the important techniques to secure digital data in the field of authentication, copyright protection and security. The non-blind watermarking systems have a main problem that for extracting the watermark image from the watermar...
متن کاملEntropy-based Image Watermarking Using Dwt and Hvs
There are a lot of wavelet-based approaches in digital image watermarking literature. In these approaches, the main issue is selection method of wavelet sub-bands’ coefficients and embedding algorithm. In this approach, an entropy-based method is proposed for non-blind watermarking of still gray level images using discrete wavelet transform. In our approach, we have also used the Discrete Wavel...
