An Adaptive Digital Watermarking Algorithm Based on Balanced Multi-Wavelet

摘要：

In this paper we propose a digital watermarking algorithm based on balanced multi-wavelet.According to the characteristics of the balanced multi-wavelet, a visual masking model based on single wavelet transformation and the JND (Just Noticeable Difference )formula are analyzed and modified, JND formula for balanced multi-wavelet transformation are obtained.The watermark extraction can be performed without the original image,so the algorithm show that the algorithm has strong imperceptibleness as well as good robustness.
