Digital watermarking is a technique for protect copyright of digital images. A good watermarking algorithm must satisfy imperceptibility, robustness and high data hiding capacity. In this paper a novel robust watermarking scheme in Hadamard transform domain for digital image is proposed. For embedding watermark bits we modify the DHT coefficient of two adjacent blocks in same position.DHT coefficient of each block is modified to bring the difference from the adjacent block coefficient in a…

Adaptive watermarking in Hadamard transform coefficients of textured image blocks

Experimental results and comparison to another Hadamard based watermarking algorithm shows that proposed algorithm has increased robustness against some of image processing attacks such as JPEG compression, resizing and median filtering, and preserved the fidelity of watermarked image very well.

Robust digital image-in-image watermarking algorithm using the fast Hadamard transform

A robust and efficient digital image watermarking algorithm using the fast Hadamard transform (FHT) is proposed for the copyright protection of digital images that can embed or hide an entire image or pattern as a watermark directly into the original image.

Digital image-in-image watermarking for copyright protection of satellite images using the fast Hadamard transform

A robust and efficient digital image watermarking algorithm using the fast Hadamard transform (FFIT) is proposed for the copyright protection of satellite images that can embed or hide an entire image or pattern as a watermark directly into the original satellite image.

Image-adaptive watermarking using visual models

This work proposes perceptually based watermarking schemes in two frameworks: the block-based discrete cosine transform and multiresolution wavelet framework and discusses the merits of each one, which are shown to provide very good results both in terms of image transparency and robustness.
