Abstract (en)
[origin: WO2016046336A1] The invention relates to a method for detecting events in a signal received on a detection sensor (22) connected to a processor (20) comprising at least the following steps, given {Ee} e=1..Ne natural events, a voting field D consisting of I subfields Di ={ [di, di+1 [ } where i=1...I and a dictionary of micro-events {mi} i=1..M: initializing, at an identical value, a table S containing score values, S[e][p], where p is a space or time position index (p ∈ D); detecting one or more micro-events mn (n=1..N), located at tn (n=1..N), (20), corresponding to the quantification of a local observation On in the signal; for each micro-event mn located at tn, for each event type "e", and for each subfield Di, updating the table S[e][tn + p] by adding a constant value for all the locations p ∈ Di, (31); and determining a set of events associated with an observation in the signal from table S, (32) and detecting the likeliest event associated with an observation of the signal.
