1. A filter device comprising:
a sensor input configured to receive a plurality of input packets from a dynamic vision sensor (DVS), wherein the DVS is configured to output a plurality of pixel values;
a coincidence detector configured to generate a plurality of thickened edges based on the plurality of input packets, wherein the plurality of thickened edges comprises a first thickened edge, and the first thickened edge indicates a coincidence between a first pixel value and a second pixel value of the plurality of pixel values, and the coincidence is detected by identifying that the first pixel value and the second pixel value have a same detected polarity;
an aggregator configured to obtain a packet payload based on event counts of the plurality of thickened edges; and
a transmitter configured to output a compressed data packet, wherein the compressed data packet is based on the packet payload.
