Now, bring history to life with a digicam

Technology allows the superimposition of a historic photo on an up-to-date snap of the same scene. But this new pic must be clicked from the same spot and the same zoom level or else the combined image looks disjointed.

However, a unique new software can now help you get your shot-framing spot on.

Frédo Durand and Soonmin Bae at the Massachusetts Institute of Technology in Boston, with Aseem Agarwala of Adobe Systems in San Jose, California, turned to a technique called visual homing to come up with the software.

Visual homing is used in robotics to send a machine to a precise location, such as a charging station.

The new software runs on a laptop linked to a digital camera. It compares the camera’s view to a preloaded historical scene and throws up instructions to adjust the camera’s position and zoom to best match the scene, reports The New Scientist.

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

The work appears in ACM Transactions On Graphics.
