Abstract

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, then the improved visual model and the modified JND formula for balanced multi-wavelet transformation are obtained. The watermark extraction can be performed without the original image, so the algorithm belongs to blind watermarking. Experimental results show that the algorithm has strong imperceptibleness as well as good robustness.
