Interesting idea. There is a blog post with more information at http://alexisvallet.github.io/posts/anime-character-detectio...

Also, it incorrectly identified two characters on the demo for me: http://a.pomf.se/pykdwz.png

Hi! Author here.

The blog post and source code refer to an older algorithm than the one in the demo. Currently it is using a convolutional network for prediction not dissimilar to [1] or [2]. I'm writing a paper about it, if there is interest I'll put it online :) .

Thank you for the feedback on incorrectly identified characters! The algorithm is not quite perfect - 70% accuracy on a randomly chosen test set.
