The proposed method uses the Quadtrees structures received by the wavelet decomposition,statistical information on the nodes and secret key to choose the locations where to embed the watermarks. One bit watermark information will be embedded into the right location.
该算法首先利用小波分解后的四叉树结构结合树节点上的统计信息和密钥来选择嵌入水印的位置,然后对确定嵌入水印的位置只嵌入1b it的水印信息。
