3. A method comprising:
receiving a plurality of input packets from a dynamic vision sensor (DVS) by a sensor input, wherein the DVS is configured to output a plurality of pixel values;
generating, by a coincidence detector, 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;
obtaining a packet payload based on event counts of the plurality of thickened edges by an aggregator; and
transmitting, to a detector, a compressed data packet, wherein the compressed data packet is based on the packet payload by a transmitter.
