Thanks for all the great resources. I think it must be obvious that we aren't image processing researchers! My background is combinatorial graph theory. But these HN comments have given us so much valuable material for improvements.

Wow, looks awesome so far. At the moment we aren't dealing with skin tones. Mostly it isn't a problem but there are some cases (such as jewellery or swimwear) where we have to use humans

Most of the guys here have more experience with text processing but we are expanding into image processing. I think we could definitely detect hair colour but it isn't that useful for Lyst. Gender identification on the other hand...(watch this space)

That's a very sensitive area to be heading into. Any assumptions you might try to make will find themselves with counter-examples quite often.

A better direction to move in might be to minimize gender differences as much as possible (although that's hard for marketing to stomach).

I mean, would one try not to recommend pants for girls or skirts for boys (kilts)? It's tricky...

I'll be curious about the gender classifier, mostly because I'm working on a statistical aging model for different gender/ethnicities. Keep on posting!
