SPIF: A Spatio-Temporal Polarity Interaction Filter for Reliable Event Selection

Remote Sensing
Event cameras provide high temporal resolution and sparse asynchronous output for small-target monitoring. However, distant weak targets often generate sparse and fragmented events that are easily obscured by responses from background structures and ...
