[Libav-user] More complex watermarking filters using DCTs etc.

Hi all,

There has been lots of research around using the discrete cosine transform
(DCT) value of blocks [1] for embedding information.

I'm wondering if there's any source code out there for these slightly more
complex and powerful watermarking filters?
