Abstract:This paper focuses on the research of digital watermark embedded in wavelet domain.The digital watermark embedded in the low frequency region is stable,but easy detected by human eyes,while is not so noticeable but vulnerable to attack in the high frequency.This paper embeds watermark both in low frequency and high frequency,and selects different embedding strength for different frequent.The author picked up the binary image of Jilin university as watermark image and made an experiment on the al...
