Any wall can turn into a camera to see the eye of the corners

An ordinary camera could soon photograph things out of sight, thanks to algorithms that interpret that light bounces off the wall.

“Normally, when light bounces off the rough surfaces, like walls, the scene reaps into a messy blurring,” says Wenwen li at the University of China’s Science and Technology, Hefei. “Our goal was to” separate “that blurred and recover the hidden scene. You mean that the rough wall turns into a mirror.”
