All Implemented Interfaces:

java.io.Serializable, EventExtractor2D

Direct Known Subclasses:

CUDAChip.CUDAExtractor

Enclosing class:

DVS128

public class DVS128.Extractor
extends RetinaExtractor

the event extractor for DVS128. DVS128 has two polarities 0 and 1. Here the polarity is flipped by the extractor so that the raw polarity 0 becomes 1 in the extracted event. The ON events have raw polarity 0. 1 is an ON event after event extraction, which flips the type. Raw polarity 1 is OFF event, which becomes 0 after extraction.
