ImageWiki

ImageWiki was a 2008 experiment in visual information sharing — an open-source image-comparison and tagging tool, written in Ruby (Merb, if you remember Merb). The idea was that you could use real images as the primary unit of communication for a wiki: visual matching to find related material, rather than hyperlinks and text.

Six of us built it: Paige Saez, Anselm Hook, Ben Foote, John Wiseman, Marlin Pohlman, Nick Brenner. BSD-licensed, hosted originally at imagewiki.org, and mentioned here mostly for the receipts — makerlab has been working on visual search and image-as-interface since well before ML-based image understanding was the default assumption.

Eventually migrated off SVN into GitHub (our first real Git migration, if anyone's counting). The 2008 code is still in the repo.
