Some amazing applications with pictures

Google has started a new feature in Google Maps, Street View. Now you can walk through selected places in the US and watch panoramic photos along the streets. This is not so new, but what is amazing is the free navigation along the streets so you can go sight seeing!
The second fascinating thing is Photosynth, presented by the TED2007 conference. Scott Hanselmann posted this information on his blog but it is really a create technology that is worth reposting. What it does is basically to align collections of images of a specific object taken from different viewpoints one to another via automatic feature extraction. What you get is a reconstructed 3D structure of the object which can be viewed as far as pictures are available. Supported is this with the seamless zooming technology of Seadragon which allows to operate with extreme large image collections in real time.
