Edge-enhanced diffractive neural networks based on spin-multiplexed nonlocal metasurfaces
Single-layer diffractive neural networks often face classification accuracy bottlenecks due to limited wavefront modulation capabilities. Edge detection, as an optical image processing technique, extracts image contours and offers a promising way to simplify classification tasks. However, integrating edge detection and...
