CityUHK researchers developed an optical corner detection imaging method using azimuthal Hilbert transform metasurfaces. This project was led by Professor Tsai Din-ping in collaboration with Professor Tao Li from Nanjing University. The study was published in Science Advances and demonstrates potential for high-speed, low-power optical processing. Inspired by biological vision, the tech focuses on local features to improve sensing efficiency. This advancement aims to reduce energy consumption in future computational vision systems.
