Abstract
An event-based sensor has an array of pixels facing a scene. The information to be processed includes events originating from the pixels depending on variations of incident light from the scene. A method includes storing a data structure for a set of pixels of the array, the data structure including, for each pixel of the set, event data associated with a most recent event originating from the pixel. Upon receiving a current event from a first pixel of the array, the method includes retrieving any event data included in the data structure for a group of pixels including the first pixel and a plurality of second pixels adjacent to the first pixel in the array. The current event is labelled based on at least one connectivity criterion between the current event and the most recent event originating from a pixel of the group.
