UW-Madison researchers and collaborators have created a computational imaging framework called photon inhibition to make single-photon cameras (SPCs) energy efficient. Photon inhibition strategically allocates detections in space and time based on vision task goals and resource constraints. There are lightweight, on-sensor computational inhibition policies that use past photon data to disable SPAD pixels in real-time, to select the most informative future photons. On real-world videos captured by an SPC, inhibition policies adapt to light levels to maintain task performance while inhibiting over 90% of photons.
