Hi,

I was wondering if someone could explain to me the Discrete Cosine
Transform, in as simple as possible English. I have attempted to
read many webpages and books on the transform but this is the first
time I have ever touched upon watermarking and malipulating images,
and I have no previous knowledge of ANY form of watermarking or
manipulating images. I really can't get my head around the process
of the DCT.

Any form of explanation that I may understand over my other sources
would be great (for example, I have tried reading <http://en.wikipedia.org/wiki/Discrete_cosine_transform>
ut I just can't make sense of it).

Many thanks,

James
