At present, much more of the wavelet-based digital watermarking algorithms are based on linear wavelet transform and fewer non-linear transform. In this paper, we propose an adaptive image algorithm transform--Morphological Haar Wavelet Transform. algorithm, original watermark decomposed with multi-scale morphological respectively. Then information is adaptively embedded into in different resolutions, combining features Human Visual System (HVS). The experimental results show that our method robust effective than ordinary algorithms.
