This looks great. I'd love to find out more about your API and what type of web scraping techniques you're using. It looks like this is going to be available publicly to developers? What type of usage do you guys allow?
I'm an interested party as well. As a student of machine learning I would love to learn the techniques you've applied. I'm doing a data mining startup and this would be very helpful.
In short, yes. The key innovation is that we've come up with a lossy, fixed-length representation of the visual features that we can use to do classification upon. I'll try to do a more detailed writeup on our blog when I find some time.
