DCT & DWT based Digital Image Watermarking using Matlab
نویسنده
چکیده
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract A process to insert a secret message or logo into the original image to provide a high level of security as the location of embedded information is secret and the watermark algorithm is not public that is known as watermarking [2].In this paper, image watermarking is done by two frequency domain techniques such as Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT).

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...

These days’ data and multimedia is taking on digital format. To protect this data from any kind of intentional and unintentional attacks, a protection mechanism is needed. Watermarking is one of the methods to achieve data authorization and security of digital data. Watermarking is the process of inserting or hiding valuable information behind a cover work. This paper focuses on two digital wat...
متن کاملEvaluating Digital Image Watermarking based on Image Interlacing , DWT & DCT .
Digital watermarking is important as it facilitates security & protection to digital data whereas when this data are used within international network they must exist in compressed format as it requires minimum transmission bandwidth & reduced storage requirement. Hence our proposed scheme will serve as a solution for maintaining the digital data in compressed state. To achieve this goal the pr...
متن کاملA Hybrid Roi-embedding Based Watermarking Technique Using Dwt and Dct Transforms
Digital image watermarking is mainly used in copyright protection. We propose block based approach for watermarking images with their own ROI. The algorithm divides the image into 8x8 blocks. DWT transform is applied on each block. The extracted LL of the computed DWT is obtained and DCT is applied on LL to obtain LL-DCT coefficients. The watermark is embedded by changing the sign of LL-DCT coe...
