Hi, I am looking for image watermarking algorithm with specified features:
1) High capacity (as much as possible, for example jpg in other jpg)
2) High robustness ( *print, make foto -> watermark should still be detectible* )
3) Algorithm should only work on image not on file headers etc...
4) It can be easly detectible for steganalisys (it is really not important) but watermark should be invisible for human eye.
Does anyone know an algorithm that meets these or similar requirements ? Where should I search more info ?
