Dear Mojtaba Mahdavi
Thanks
for replying, from the papers which I read, I understood that invisible watermarking( for images) is under the umbrella of
steganograpgy, but visible Digital watermarking is not.
Thanks for your comment.
I need the following paper:

and Applications to Watermarking, (EMAST'96) European Conference on Multimedia Applications Services and Techniques,
Louvain-La-Neuve,. Vol. 2 1996. pp. 687-695.may 1996.
if any one of you have it, plz forwored it to
me.
thanking you.
