Using Curvelet transform for watermarking based on amplitude modulation
In this paper we propose a precise and robust watermarking scheme based on the technique called amplitude modulation. A watermark is embedded in a color image by modifying the pixel values in the blue channel. At the receiver, the watermark bits are retrieved using a prediction system, by a linear combination of nearby pixel values around the embedded pixels, and without having the original ima...

متن کاملDigital Image Watermarking Algorithm Based on Fast Curvelet Transform
A digital image watermarking algorithm based on fast curvelet transform is proposed. Firstly, the carrier image is decomposed by fast curvelet transform, and, the watermarking image is scrambled by Arnold transform. Secondly, the binary watermarking image is embedded into the medium frequency coefficients according to the human visual characteristics and curvelet coefficients. Experiment result...
متن کاملMultiple Watermarking Algorithm Based on Spread Transform Dither Modulation
Multiple watermarking technique, embedding several watermarks in one carrier, has enabled many interesting applications. In this study, a novel multiple watermarking algorithm is proposed based on the spirit of spread transform dither modulation (STDM). It can embed multiple watermarks into the same region and the same transform domain of one image; meanwhile, the embedded watermarks can be ext...
متن کاملAudio Watermarking Based on Wavelet Transform and Quantization Index Modulation
In this paper, we present a technique for embedding digital watermarks into digital audio signals. Watermarking is a technique used to label digital media by hiding copyright or other information in the underlying data. In the case of digital audio, the main constraint is the tradeoff between robustness and imperceptibility, as hearing is one of the most sensitive human senses. In our method, t...
