Dynamic Low-light Imaging with Quanta Image Sensors [PDF]
European Conference on Computer Vision, 2020 Imaging in low light is difficult because the number of photons arriving at the sensor is low. Imaging dynamic scenes in low-light environments is even more difficult because as the scene moves, pixels in adjacent frames need to be aligned before they ...
