There is surely one for MS-MSSIM since S & B originally wrote this in
Matlab. Usually, you can download the code from their home page.

http://www.ece.uwaterloo.ca/~z70wang/research/ssim/

It is actually one of the first hits that come up - did you try google?
(-:

Please check whether there's a multiscale version available on the page
- the single-scale version doesn't really perform very well IMHO.

There is AFAIK no matlab version of VDP, it's C++ only (and there's
nothing bad in using that instead of matlab. :-).

There was also a work based on DCT by Ponomarenko et al, using matlab,
unfortunately their web-page seems to be down:

http://www.cs.tut.fi/~ponom/psnrhvsm.htm

On Sheik/Bovik's home page, you'll also find the matlab source for
"VIF", another model. I haven't used that yet, so I can not comment on
it, but feel free to try.

So long,

Thomas
