[WM]: Watermarking in LPM Domain

[Vallabh Chilakapati <vallabhc@yahoo.com>]

Hi all,
I am working on a watermarking technique which utilises Log Polar Mapping and DFT to achieve rotation, scaling and translation (RST)
invariance. I wrote the code but it is somewhere going wrong. In almost all the papers that I have refered in this regard, I found
that it is practically difficult to implement this kind of technique. 
If you got a working code in this regard or if you are interested in this technique, with basic knowledge on LPM, please send me a
personal mail at vallabhc@rediffmail.com
 
Thanks,
Vallabh C
