green heft
基本解释
- [计算机科学技术]绿色分量
专业释义
- 绿色分量
Received embedded watermarking information image block through DCT transformation,and merged it into the whole plan through DCT inverse transformation;then,received watermarking information gray image of green heft. Finally the watermarking color image was received through channel compound.
即将Arnold置乱加密后的水印图像嵌入宿主图像绿色通道的DCT中频系数中,再对原始图像进行通道分离获得绿色分量,由DCT变换得到嵌入水印信息图像分块并DCT逆变换后将其合并成整图,得到加载水印信息的绿色分量灰度图,最后合成通道得到含水印的彩色图像。
