The optical flow estimation task in computer vision is that given two images $\mathcal{I}_1$ and $\mathcal{I}_2$, we want to estimate for each pixel in $\mathcal{I}_1$, where it goes to in $\mathcal{I ...

Photonics researchers have introduced a novel method to control a light beam with another beam through a unique plasmonic metasurface in a linear medium at ultra-low power. This simple linear ...
