摘要：Watermarking algorithms can be implemented using simple and direct calculations in time domain embedding as replacing the least significant bit (LSB) of the original image pixels, it also can be implemented using more complex but more robust transform domain based embedding by changing coefficients values. In this paper, a new method of using a combination between the transform domain and time domain watermarking is presented by embedding the watermark within the approximation band coefficients of LWT transform. This method will combine the simplicity of time domain watermarking and the high performance of transform domain watermarking. The choice of the coefficient bit in certain image block is based on the amount of texture in that block. The texture amount is calculated using a low complexity texture mapping model. The experimental results shows high quality watermarked images since a small portion of image is used for the embedding process.
