David Held, an assistant professor in CMU's Robotics Institute, said depth cameras, which shine infrared light on an object to determine its shape, work well for identifying opaque objects.

New experiments show that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material. Materials such as paper ...

“The real advantage to the ColorPlus-R is the ability now to recognize the color of an opaque object with extreme confidence and in a fraction of a second,” says NRT President Matthias Erdmannsdoerfer ...

The light from infrared cameras passes through the objects and gets scattered in the process, and depth cameras have trouble determining the proper shape without opaque surfaces. The result of all ...
