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 downsampling is regularly used in standard computer vision, there are no reliable techniques to do this for event data, resulting in a bottleneck for event-based computer vision systems. Here we extend our previous work, explain the challenges that need to be overcome by any effective event-based downsampling algorithm and present a novel biologically-inspired process that can adeptly downsample event streams by factors of up to 16 times compared to the original resolution. We show that our downsampled event streams achieve high fidelity with a hypothetical low-resolution event camera and improve classification performance on highly downsampled versions of the DVS gesture dataset. Furthermore, we demonstrate that compared to a naïve event-based downsampling, our approach massively reduces the number of spikes that downstream neuromorphic processors have to handle.
