It considers the green component and blue component characteristics of original color image. First, green and blue components are transformed in discrete wavelet transformation.
算法考虑了原始彩色图像的绿色分量和蓝色分量的特点,首先将绿色和蓝色分量进行离散小波变换,然后将水印图像进行混沌系统加密预处理,最后将水印序列嵌入在绿色和蓝色分量的具有较大JND值所对应的低频系数上,实现了水印的盲提取。

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。

大多数电视都接受分量视频，有些计算机监视器也支持。分量视频的效果与早期的vga类似，只是它带有三个RCA连接器，一个输出红色，一个输出绿色，一个输出蓝色。
Component video, mostly accepted by TVs, but also by some computer monitors, is very similar to plain old VGA, only it comes out as three RCA connectors, one red, one green, and one blue.
例如，假设阈值被设置为0.7，并且您正在呈现一种颜色，其红色、绿色和蓝色分量分别为230、50和220。
For example, suppose the threshold is set to 0.7, and suppose you are rendering a color whose red, green, and blue components are 230, 50, and 220, respectively.
