But it is awesome.
[1]: Assumptions about the 'quantity of art' inherent in painting versus photography seem to be playing a role. Both are typically flat images and are computationally fungible. So maybe photo styled to photo might be a different training set. It's not that radically different from etching applied to photograph.
[2]: anyway, still an awesome project. What I imagined is something that could have subtle effects on a photograph as an artistic tool for photographers...because that's my bias.
At one point my graphics card driver had to restart. Not sure what happened there as I was not able to reproduce the problem.
What about making a short video or an animated gif? Is the transformation smooth? (Is the image at 53.2% similar to the image at 53.3%?) Or the texture is rearranged in a random way?
You can probably calculate some key points in the bar while the user is wandering, and then use them. This will kill the battery of the cellphones, so perhaps don't enable it by default.
