There’s a new camera system so sensitive it can recognize what it’s looking at using just five tiny specks of light.

Machine vision with small numbers of detected photons per inference

The Takeaway
Standard digital cameras require billions of photons to form a recognizable image. This technology uses a 'neuromorphic' approach to identify patterns in near-total darkness, effectively allowing computers to 'see' using light levels that are thousands of times lower than what conventional sensors require.
From the abstract
Machine vision, including object recognition and image reconstruction, is a central technology in many consumer devices and scientific instruments. The design of machine-vision systems has been revolutionized by the adoption of end-to-end optimization, in which the optical front end and the post-processing back end are jointly optimized. However, while machine vision currently works extremely well in moderate-light or bright-light situations -- where a camera may detect thousands of photons per
