We get the extracted matrix through the scrambled watermark and low-frequency sub-image after wavelet transformation.
本文提出了一种基于图像置乱和小波变换的零水印算法:首先将水印图像进行置乱,然后利用载体图像一级小波分解后的低频子图和置乱后的水印图像得到提取矩阵,再对提取矩阵进行一定的打乱加密。
This article has introduced an array technique,reduce the FP-Tree traversal time on mining frequent item sets so that the method can be sped up.
为了克服Apriori算法在挖掘最大频繁项集上的不足,以及FP-Tree存储结构算法多次遍历的缺点,本文引进了新的矩阵技术,减少了FP-Tree遍历次数来挖掘频繁项集,提高了挖掘频繁项集和最大频繁项集效率。
