D2: Technologies, devices, circuits, and algorithms for neuromorphic event-based vision system


Dissemination Workshop


13:30 - 18:00


Room 5A


The concept of neuromorphic events can be broadened beyond the conventional intensity change detections. For higher-level cognitive tasks, events of varying complexity are refined from simpler ones. The workshop introduces complex-event neuromorphic algorithms co-developed with sensors and computing hardware. Higher-level cognition algorithms operate with lower temporal rates than those designed for reflexes requiring immediate response to sensory data. Data transmission bottlenecks affect where simple events are transformed into more complex ones. Beyond-CMOS devices are widening the capabilities of the system in comparison to CMOS-only solutions. The workshop presents ideas and outcomes from the MISEL EU-project on neuromorphic sensing and computing, with additional insights from acknowledged experts in the field.
