Diego Gutiérrez, Adrián Jarabo and Ibón Guillén of the University of Zaragoza, together with researchers from the University of Wisconsin-Madison, developed this new computational vision technique.
In 2013, this same team, in collaboration with MIT, developed a camera capable of capturing light at a trillion frames per second.

Since this discovery, several teams of scientists from around the world have been trying to use this technology to see through the corners, but apparently insoluble problems existed.

To fix them, this team has designed a new computational model that allows a wall to be used as if it were a virtual camera that captures the hidden scene.

Basically, at a trillion fps, you can approximate the path of each photon when traveling through the scene and then mathematically reverse the path of millions of photons and reconstruct a scene.

From now on it will be easier to escape from the sponger or the creditors and robbers that lurk behind the corners.
