2D edge detection with TPPs in a simple layer stack. Credit: ACS Photonics (2024). DOI: 10.1021/acsphotonics.4c01667 Physicists from the group of Jorik van de Groep at the UvA-Institute of Physics have devised a new method that can be used to detect edges of images in an extremely energy efficient and ultrafast way. The results were recently published in the journal ACS Photonics. The energy cost of computation and data processing has become one of the most significant energy problems for our so...
