Mine doesn&amp;#x27;t need anything like CUDA or OpenCL, and runs on a 6 year old laptop at 1280x720@15fps.&lt;p&gt;I ran it at our free, ticketless convention called Makevention (bloomington, IN). Estimates were that 650-700 people showed up. My tracker counted 669 uniques, which I think is spot on.&lt;p&gt;I also wrote mine for privacy in mind. The database was a KNN on a perceptual hash of the face. The data that was stored was only a hash and could only verify a face: it could not generate the face from the hash. Considering the application (Maker&amp;#x2F;Hacker con) I wanted to be sure that this was the case. (The data only resided on that machine, and it&amp;#x27;s wiped now.)&lt;p&gt;I&amp;#x27;ve halted work on the &lt;i&gt;gui&lt;/i&gt; version of it. Now I want to make it into a client&amp;#x2F;server, where the clients are RasPis (or other cheap compute with camera) and the server is whatever good machine you have. Initially, I&amp;#x27;ll reimplement the same algo, but I know that KNN has exponential time&amp;#x2F;cpu requirements the more samples I get.</text><parent_chain></parent_chain></comment><story><title>OpenFace: Free and open source face recognition with deep neural networks</title><url>http://cmusatyalab.github.io/openface/</url></story>
