Robust watermarking of color images based on the Discrete Wavelet Transform

نویسنده

  • Ovidiu COSMA
چکیده

This article presents a method of semi-blind watermarking based on the discrete wavelet transform, that uses the chrominance components of the image for watermark embedding. The watermark is resistant to usual image processing operations such as compression, noise addition, cropping, histogram adjustment and filtering. Keywords—watermarking;discrete wavelet transform

An improved hybrid image watermarking scheme in shearlet and wavelet domain

Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...

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...

A Robust HDWT-DCT Based Watermarking Scheme Against Cropping Attacks

In this paper, we propose a watermarking technique based on Haar Discrete Wavelet Transform-Discrete Cosine Transform (HDWT-DCT) by using matrixbased Two-dimensional Linear Discriminant Analysis (2DLDA) for color images. By embedding the reference watermark and using matrix-based 2DLDA scheme, we do not need all the embedded information of watermark and apply only part of matrix-based samples f...

Blind Watermarking Scheme Based on Rdwt-dct for Color Images

In Digital era sharing of images have become very common and raises the risk of using it for unethical and fraudulent purposes with the help of manipulation tools. Digital image watermarking is one way to protect the digital information (text, images, audio, and video) from fraudulent manipulations. Digital Image Watermarking is a process of implanting data in the original image for authenticat...
