Abstract
Event-based (EB) vision sensors pixel-individually detect temporal contrast exceeding a preset relative threshold [1], [2] to follow the temporal evolution of relative light changes (contrast detection, CD) and to define sampling points for frame-free pixel-level measurement of absolute intensity (exposure measurement, EM) [3], [4]. EB sensors gain popularity in high-speed low-power machine vision applications thanks to temporal precision of recorded data, inherent suppression of temporal redundancy resulting in reduced post-processing cost, and wide intra-scene dynamic range operation.
