Image with Less InformationWatermarking Algorithm Based on DWT

In this paper two definitions which are respectively called white image and pseudo-binary image are given through certain mapping relations, we propose a white image and pseudo-binary image watermarking algorithm based on discrete wavelet transform (DWT). This algorithm directly embeds binary image watermarks into wavelet transformation domain of the white digital image and pseudo-binary image, inserted watermark realized the watermark information strong robustness under the guarantee of the highly transparent premise. Moreover, the algorithm is also suitable for the common text image watermark. The experimental results show that this algorithm is feasible.
