Event-based cameras (Lichtsteiner et al., 2008; Posch 2010; Gallego 2020) operate fundamentally different from frame-based cameras: Each pixel of the sensor array reacts asynchronously to relative brightness changes creating a sequential stream events in address-event representation (AER). event is defined by microsecond-accurate time stamp, position and binary polarity indicating increase or d...

We present a system for online, incremental composite event recognition. In streaming environments, the usual case is data to arrive with (variable) delay from, and be revised by, underlying sources. propose RTECinc, an version of RTEC, recognition engine formal, declarative semantics, that has been shown scale several real-world streams. RTEC deals delayed arrival revision events by computing ...
