Vibration measurement with neuromorphic vision sensors

Mechanical Systems and Signal Processing
In this paper, a novel methodology for vibration measurements of flexible structures with neuromorphic vision sensors (i.e. event cameras) is proposed and validated. Unlike conventional frame-based sensors, event cameras asynchronously record changes in scene brightness, enabling high temporal resolution with reduced data redundancy.

Applying neuromorphic vision sensors to planetary landing tasks [PDF]

2009 IEEE Biomedical Circuits and Systems Conference, 2009
Recently there has been an increasing interest in application of bio-mimetic controller s and neuromorphic vision sensor s to planetary landing tasks. Within this context, we present combined low-level (SPICE) and high-level (behavioral) simulations of a novel neuromorphic VLSI vision sensor in a realistic planetary landing scenar io.
