Now, bring history to life with a digicam
There's good news for all the history fans! Scientists have come up with a new technology that allows the superimposition of a historic photo on an up-to-date snap of the same scene.india Updated: Jul 26, 2010 12:56 IST
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.
