A method of producing a motion filter for detecting point targets moving slowing within a sequence of readjusted binary images, these images corresponding to a history at the instant n-1, denoted Hist n-1 (1), including target trajectories and alarms. This method includes: A) an initializing step having a sub-step of accumulating results arising from an extractor and which consist of the coordinates hj of the start-points of trajectories and of the coordinates Ci in Hist(n-1) (1); B) a step for constructing the history at the following instant n, denoted Hist N (2), having two loops: B1) a first loop for producing either the lengthening or the initializing of the trajectories depending on the alarms received; B2) a second loop for producing either the lengthening or the destruction of the trajectories not depending on the alarms received; C) a step for detecting the targets from observation of Hist n (2).
