摘要：
based on the in-depth study of continuous wavelet and discrete wavelet transform theory, this paper proposes a digital watermarking algorithm of the gray-scale images based on discrete wavelet transform (DWT). The results show that this algorithm not only makes the embedded watermark have good invisibility and the ability against various attacks, but also has strong robustness.
