If you're interested in image processing and image search, and you want to quickly get up to speed with current technology, take a look at PyImageSearch, and tell Adrian we sent you! He'll have you doing stuff like face detection and OCR in no time. Seriously, if you like to learn by doing, he's got cookbooks to get you started and offers advanced training from there. We're talking 15 lines of code, and you're detecting objects! And if you like theory, you get to learn about the state of the art, and can then deepen your knowledge in areas important to you.

At PicLookup, we're pretty good at fast search, but we're getting interested in AI, Deep Learning, and all that stuff, which is how we found Adrian's site.
