“Smile for the computer!” Crowdsourcing better portraits

Interesting exploration from researchers at Adobe (including Aseem Agarwala, who just joined Google) and Berkeley:

[T]rain a model that can automatically predict attractiveness of different expressions of a given person. We also train a cross-subject model that evaluates portrait attractiveness of novel subjects and show how it can be used to automatically mine attractive photos from personal photo collections. Furthermore, we show how, with a little bit ($5-worth) of extra crowdsourcing, we can substantially improve the cross-subject model by “fine-tuning” it to a new individual using active learning. Finally, we demonstrate a training app that helps people learn how to mimic their best expressions.
