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 ...
The distribution of the wavelet coefficients in 2-D discrete wavelet transform (DWT) subspaces can be well described by a Gaussian mixture statistical model. In this paper, a secr...
In this paper, a digital image watermarking technique based on Discrete Wavelet Transform (DWT) will be proposed. This scheme is designed utilizing principles deriving from the hu...
