Generally, the code is very hacky, and (for example) the user may need to do a lot of steps to run it, many counter intuitive.
In the Mythical Man-Month, Fred Brooks says that to go from a prototype that does everything you want, to one with nice packaging, takes 3x the effort. I'm not sure about the 3x number, but it does take a lot of effort.
Most might not have the licensing issues. I'm not sure on the copyrights for things like Viola-Jones or Active Shape Modeling. I know Cootes has refused to release the source for his modeling software in case their financial incentive.
The software is out there, I'll link some if you want. What you are really looking for is the training data used to create the faces though. That is where the money is.
I have a feeling that's very common. I recall a big to-do about Cortexica and their brain-inspired computer vision algorithm. They built it into an iPhone wine label recognition app, which currently has two ratings; both one-star.

Why do they never release the applications for these things? Copyright?

I always assumed they planned to create a commercial product. And maybe they do and we never hear of it.
