Event-based spatio-temporal down-sampling

Abstract—As vision sensors for autonomous systems, event based cameras provide numerous benefits over conventional cameras including higher dynamic range and temporal resolution as well as lower bandwidth and power requirements. However, while down-sampling is regularly used in standard computer vision, there are no reliable technique to do this for event data, resulting in a bottleneck for event based computer vision systems. Here we propose two novel methods for down-sampling event data and compare them against a previously used metho
