Abstract
For processing a signal from an event-based sensor having an array of sensing elements facing a scene, the method comprises: receiving the signal including, for each sensing element, successive events originating from said sensing element depending on variations of incident light from the scene; analyzing the signal to detect a frequency pattern in a light profile sensed by at least one sensing element; and extracting information from the scene in response to detection of the frequency pattern.

A method of processing a signal from an event-based sensor, the event-based sensor having an array of sensing elements facing a scene, the method comprising:
- receiving the signal including, for each sensing element, successive events originating from said sensing element depending on variations of incident light from the scene;
- analyzing the signal to detect a frequency pattern in a light profile sensed by at least one sensing element;
- and
- extracting information from the scene in response to detection of the frequency pattern,
- wherein extracting information comprises demodulating frequency patterns detected in the scene.
