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.
