Finding Familiar Faces with a Tensorflow Object Detector, Pytorch Feature Extractor, and Spotify’s Annoy

In a few different posts I have put together facial recognition pipelines or something similar using object detectors and something like a Siamese network for feature extraction to find similar images but I haven’t really dug into how to use those feature vectors in a more practical larger scale way. What I mean here is that you don’t want to have to go ahead and do pairwise comparisons across your entire database, it just isn’t practical. So in this post I am going to demo how to…
