Description Détection de mode d'une densité 2D par mean shift: cas d'une image de probabilités de teinte chair. L'étendue de l'objet à segmenter est supposée (taille de la fenêtre W fixe) et la position initiale de W est à fournir (manuellement, à l'aide d'un détecteur ou en utilisant des informations temporelles dans le cas de séquences d'images). A chaque itération le vecteur déplacement de W se nomme le mean-shift, et l'ensemble des positions successives est la trajectoire du mean-shift. La trajectoire du mean shift est le résultat d'une montée de gradient, elle peut éventuellement converger vers un maximum local secondaire, notamment si l'initialisation de W est peu judicieuse.
