About Me

PBX I'm Paul Bissex. I build web applications using open source software, especially Django. Started my career doing graphic design for newspapers and magazines in the '90s. Then wrote tech commentary and reviews for Wired, Salon, Chicago Tribune, and others you never heard of. Then I built operations software at a photography school. Then I helped big media serve 40 million pages a day. Then I worked on a translation services API doing millions of dollars of business. Now I'm building the core platform of a global startup accelerator. Feel free to email me.

Book

I co-wrote "Python Web Development with Django". It was the first book to cover the long-awaited Django 1.0. Published by Addison-Wesley and still in print!

Software for determining image similarity?

This is a lazyweb request -- I'm looking for something but I don't even know if it exists. I have about 200 photos (headshots) and I'd like to make an animation that runs through them in order of, for lack of a better term, visual similarity. I'm not talking about morphing or just fading between the images in arbitrary order. Is there software out there that, given a reference image and a set of images to select from, can choose the most similar image? Open source would be best, as there's no budget for this, and command-line-only is fine, but I am on a Mac.

Not exactly what you are looking for but, if you do not already know it, try to see at imgSeek (written in Python):

This is only vaguely related. There is a project that does exactly this with geospatial imagery. You give it an image and it will search sattelite imagery from around the globe to find a match. Unfortunately, it is only available to the U.S governement right now. Here's a demo clip:

That's cool, too, thanks.

I had a chance to try out imgSeek -- once I installed Qt/Mac -- and it's pretty amazing. The command-line tool is absolutely usable for the purpose I have in mind. Now to find the time...

I wrote a small image similarity library for the iphone. I run it with my iPhone AppStore app called eyeBuy which compares an image against a database of more than 5 million (and growing). So your 200 would be a breeze.

I posted an SDK at: http://sites.google.com/site/imagecomparison/ and could compile it into an OSX library is there is interest. Email me at brett dot spurrier at gmail.com.
