Abstract
Disclosed is a method for processing an asynchronous signal produced by a light sensor, the sensor having a pixel matrix disposed opposite a scene, the method including: receiving from the light sensor the asynchronous signal including, for each pixel of the matrix, successive events from the pixel; analysing the asynchronous signal using activity profiles as events are received in the asynchronous signal. The activity profile includes at least, for each pixel of the sensor, an activity value that decreases as a function of the time that has passed since the most recent event among the successive events from the pixel.
