“Computational Rephotography” helps marry new & old

Remember the Historypin project I mentioned recently? Creating that kind of historical overlay is about to get easier.

“Computational rephotography,” says Wired, “is a fancy name for photos taken from the exact same viewpoint as an old photograph. Actually, that’s just rephotography. The ‘computational’ part is when software helps out.”

Adobe researcher Aseem Agarwala, together with MIT’s Frédo Durand and Soonmin Bae, are developing some interesting tech here:


According to New Scientist,

The team’s software runs on a laptop linked to a digital camera. The software compares the camera’s view to a preloaded historical scene and provides instructions to adjust the camera’s position and zoom to best match the scene.

The laptop is a temporary measure, however: “We envision the tool running directly on the camera,” the team says.

Video: Lightning in ultra slow-mo

Neat: two seconds of lightning slowed down to a minute and a half.
