[WM]: Blind robust watermarking schemes

["Jae-Won CHO" <cho@creatis.insa-lyon.fr>]

Dear Mr. Zafeiriou.

Recently, I read your paper,
=A1=B0Blind robust watermarking schemes for copyright protection of 3D =
mesh objects=A1=B1, IEEE Trans. On Visu. And Comp. Graph. Vol. 11,
No. 5, 2005

I have some question for the paper.

In Fig. 9, you used Foot model with 25845 vertices and 51690 faces.

First, does your scheme single bit embedding scheme or multi-bit one? If =
the method is multi-bit embedding, then I wonder how many
watermark bits are embedded in this model.

You mentioned that it has 126.8 dB of SNR without an attack, and I think =
it is very good result.
I would like to know the number of modified vertices of the watermarked =
Foot model (without an attack).

Thank you for your response.

Sincerely,
J.W. CHO
