不变嵌入
invariant imbedding
- 首先对图像进行分块，分别提取每块图像的直方图不变矩，组合起来作为数字水印，然后利用奇异值分解的方法将这些水印嵌入到原图像中。
First we go on blocking to image an extract moment invariant of histogram from the blocking image and combine it as the digital watermarking. - 根据不变嵌入原理来寻找最优策略，给出了多阶段SUE配流模型与算法。
The optimum strategy based on fixed embedding principle is determined and a multi-period SUE assignment model as well as the algorithm is given. - 多核设计的优点是在频率不变的情况下让处理器的性能获得明显提升，这一点将是未来嵌入式系统的发展趋势。
The multiple-core design's merit lets processor's performance in the frequency invariable situation obtain the obvious promotion, this will be the future trend of the development of embedded systems.
