摘　　要：设计了基于局部特征自适应滤波的图像水印算法。该算法假定已知电子设备的退化参数,利用二值化自动生成数字水印信号,然后利用电子设备获取的图像局部特征的自适应滤波特性,设计了水印信号嵌入算法和水印信号提取算法。最后,对提出算法进行验证。验证结果表明,算法具有较好的不可见性和鲁棒性。The image watermarking algorithm is designed based on local feature adaptive filtering. First, The algorithm assumes that the degradation of the known parameters of electronic devices, watermark signal is auto- matically generated by the binary, then, by using the electronic device to obtain images of the local feature adaptive filtering properties and designed watermark embedding algorithm and the watermark signal extraction algorithms. Finally, the experimental results show that the algorithm has invisible and robustness.
