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。

Experiments show that there is an approximate linearity in quite a large range for the red and green components. The green component is even more active than the red, but the blue is inferior.
实验表明,红、绿分量在相当大的范围内有近似线性,绿分量甚至比红分量的贡献更大,而蓝分量的贡献较小。
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.
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。
