What is Photosynth?

• Photosynth is a software application that analyzes digital photographs to build a three-dimensional models.

How does it work?• Step 1

– Software analyzes multiple photographs taken of the same area.

– Each photograph is processed using an interest point detection.

– An algorithm detects similarities between points and, essentially, connects the dots.

• Step 2– The next step is to create the 3D model,

which is done with a Photosynth viewer.– The viewer is free to download– The viewer is stored on the users

computer, but the photos are stored with on a Microsoft server.

Features• Zoom in and out of photos• Maneuver through a scene to see

photos at different angles• Send photos

Limitations?

• The maximum amount of space Microsoft provides is 20GB.– Which equates to approximately 60

‘synths’ of 150-200 photos each.• Also, you can’t add photos, they all

need to be uploaded at once for a project, Microsoft is working on this complaint though.

More Limitations?• Takes practice to get the right shots• Only runs on XP and Vista• Lastly, to get a really good ‘synth,’ a lot

of pictures need to be taken.

Applications

• Creative way for consumers to store, and organize photos.

• It is also planned to be a back end programming tool for Virtual Earths.
