摘　　要：论文提出一种新的基于序列假设检验的数字水印双门限检测算法,它能很好地抵抗各种水印攻击,提高了检测概率。实验证明序列检测方法在满足一定检测性能的条件下,比普通检测器的检测速度平均快66%,可用于检测视频水印,搜索大型数字数据库中的水印等。The paper analyzes a new watermarking detection paradigm including double detection thresholds based on sequential hypothesis testing. The paradigm has good immunity to host signal attacks and high detection probability. Many experiments prove that the above framework can detect watermarks about 66% faster than popular detectors. It could potentially have significant impact on many applications such as video watermarking detection and searching for watermarks in a large database of digital contents.
