A method for detecting events in a signal received on a detection sensor linked to a processor comprises: given events of nature {E}, a domain of votes D composed of I sub-domains D={[d, d[} with i=1 . . . I and a dictionary of micro-events {m}, initialize to an identical value an array S containing values of scores, S[e][p], where p is a spatial or temporal position index (p&#x2208;D), detect micro-events m(n=1 . . . N), located at t(n=1 . . . N), corresponding to a quantization of a local observation Oin the signal, for each micro-event mlocated at t, for each type of event 'e', for each sub-domain Dupdate the array S[e][t+p] by adding a constant value for all locations p&#x3f5;D, determine a set of events associated with an observation in the signal on the basis of array S, and detect the most probable event.
