All Implemented Interfaces:

java.io.Serializable, EventExtractor2D

Enclosing class:

DVS320

public class DVS320.DVS320Extractor
extends RetinaExtractor

The event extractor. Each pixel has two polarities 0 and 1. There is one extra neuron which signals absolute intensity. The bits in the raw data coming from the device are as follows. Bit 0 is polarity, on=1, off=0
Bits 1-9 are x address (max value 320)
Bits 10-17 are y address (max value 240)
Bit 18 signals the special intensity neuron, but it always comes together with an x address. It means there was an intensity spike AND a normal pixel spike.
