I have given a lot of thought to this subject before, but I didn't think the technology was good enough yet. Now with deep dream and facebook's Eyescream, DRAW, and Google's DeepStereo, generated images are becoming practical.
Someday we will have something like a totally automated photoshop. You can just ask it to make a photo, and it will produce it. Then you can tell it how to tweak it. Or it can give different versions and you can pick which you like most, and repeat (see http://picbreeder.org/, which also uses neural networks, but imagine it has an actual model of natural images instead of starting from scratch.)
It need not be limited to static images and could eventually do videos.
Generated porn that meets everyone's weird fetish is the most obvious application.
I also think colorizing black and white photos will become a popular niche application. And all sorts of other simple photo enhancements and tools.
These are very good ideas: Things that I half knew already but didn't really admit: artwork generation and it's viability for sale. Thing that I hadn't extrapolated to yet: video generation. neat application: pornography - neat! I hear it makes lots of money!
Colourizing already exists, but its not that great/we don't care enough to have seen it take off.
I am looking into artwork generation to see where it can go.
According to my reading of the license it should be fine to sell images (generate an artwork and sell it); as long as you don't try to sell the code to anyone.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
