Some time ago I played and wrote about Photosynth. Now a couple of days ago I watched a demo of the technology behind the software at TED 2007. You can see the demo on the TED site. The Microsoft employee mentioned there the code name for the technology “Sea Dragon”. Again another term that worth search it for on your favorite search engine.

It is amazing to see how easy they are playing with images which are big. And I mean BIG (tens of gigapixels, maybe even more). It is more amazing to see how easy and fast they are able to look (visual search) for all kind of visual features in the big image.

It is so easy to look for human faces in a video surveillance “tape” that is scary. Also the availability of video surveillance equipment especially in big cities is scaring. If you put these technologies together than makes sense for the conspiracy theorist in me to say that “they” and I do no mean Microsoft, were using this kind of technology for years most probably tens of years.
