Claim One:
1. A method of tracking a target in a sequence of images representing a scene, the method comprising, for each current image: a step of detecting objects in the scene, each object detected being characterized by a position and a dimension in the current image, a temporal association step, in which an attempt is made to associate each object detected in the current image with an object detected in the previous image of the sequence as claimed in their respective positions in the images, each set of objects detected in a continuous sequence of images forming a tracklet, one of the tracklets being assigned to a first target, a step of determining a second target in the current image, the detected object best corresponding to a given search area determined for a previous image of the sequence being assigned to the second target, a step of comparison between the identity of the detected object assigned to the first target and the identity of the detected object assigned to the second target, in the case of different identities, a step of determining the detected object that best corresponds to a dynamic of a final target, in the case where the first target best corresponds to the dynamics of the final target, a step of updating the search area for the current image based on the position of the first target, in the case where the second target best corresponds to the dynamics of the final target, a step of updating the search area for the current image based on the position of the second target, and a step of searching for the final target in the search area for the current image by comparing areas of the current image with a reference model representative of the final target.
