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.
