A fab round-up of some recent Google research projects. Including… analyzing and searching Arabic text … help children aged 5 to 13 find what they are looking for … a system to measure distances in Flickr-sized collections of images (presumably leading to “show me long sweeping views” filter, and possibly to automatic geo-location of photographs in Google Earth) … and more.

Depth-sensing is, of-course, potentially on the way in pocket s-3D digicams. Depth information would be encoded in the image metadata, as a by-product of stereo-3D imaging.
