Thread Subject: color image watermarking

Helloooooooooooo every one.

We know that an rgb image is composed from red ,green and blue.
In a color image watermarking you must embed a watermark image into one of the channel (red,green ,blue),or you must work on one of them.

So ,I have read some paper about color image watermarking ,and no one of them work on the red channel.

My question is why we don't use the red channel for watermarking ?
I think in evrey color image (RGB image) ,the red has the biggest entropy .

This isn't really a MATLAB question, so you might receive more interest on
an image processing specific group, like sci.image.processing. If your news
server doesn't carry it, you can access it via Google groups
(http://groups.google.com) or other news providers.
