I don't know how to exlain it more simply THE ONLY WAY TO GET TO THE LOW FREQUENCIES IS TO ZIGZAG THE DCT SPECTAR IN A ROW OR A COLUMNE READ THIS TUTORIAL ABOUT JPEG COMPRESSION AND I HOPE THIS CLEARS THINGS UP SOMEHOW **broken link removed**
if the coverimage(x*Y)~=pnsequence you'll have an error, it may not be a goog idea to implement a hibrid sceme, as the high corelation of the coverimage will destroy the caracteristics of the pn string m~=0; sigma~=1; So use eather the stamping or watermarking scheme not bouth; :idea:
