| Abstract: | The basic principles of image digital watermarking was analyzed,and an adaptive image watermarking algorithm based on wavelet transform was proposed through the analysis of wavelet basis function,decomposition series,coefficient selection and human visual masking.This algorithm was tested in several commonly used means such as shearing,noise adding,filtering,sharpening,fuzzy,etc.The experimental results show that the algorithm has strong robustness. |

| Keywords: | digital watermarking wavelet transform the human visual system |
