DWT-DCT-SVD based watermarking
Some works are reported in the frequency domain watermarking using Single Value Decomposition (SVD). The two most commonly used methods are based on DCT-SVD and DWTSVD. The commonl...

Spatially Adaptive Wavelet Thresholding for Image Watermarking
In this paper, we introduce a new robust image watermarking technique based on the Discrete Wavelet Transform (DWT). The proposed method extends the concept of image denoising to ...

A new data hiding method using angle quantization index modulation in gradient domain
A robust data hiding scheme that embeds the watermark bits by quantizing the gradient directions of an image is proposed. By embedding the watermark in the angle, the watermark be...

Quantization Based Blind Watermarking Algorithm Using DWT
- In this paper a Discrete Wavelet Transform based blind watermarking algorithm is proposed for embedding a grayscale watermark into a grayscale image. A new approach of choosing t...
