The extracting scheme detects watermark by embedding positions and weighting factor associated with the full-scale information for conditions of JPEG loss compression,blurring,sharpening and geometric distortions(i. e. ,cropping and affine transform).
分别在JPEG有损压缩、模糊、增强、几何攻击(裁减和仿射变换)的情况下,根据算法中的嵌入位置和加权因子,并利用全尺度信息进行了水印提取,并用峰值信噪比(PSNR)和相关系数进行嵌入前后图像和水印的比较。
