Abstract: The present invention relates to a method of tracking objects in a scene observed by an event-based sensor that produces events asynchronously from a matrix of sensing elements, wherein, from each sensing element of the matrix, respective events are produced as a function of variations of light incident on the sensing element, the method comprising: detecting, by a first process, an object in the scene from asynchronous events produced by the event-based sensor; and determining, by a second process, a track associated to the detected object from asynchronous events produced by the event-based sensor; wherein the first process has a time resolution lower than the second process.

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.
