The first one is using a classical grey level conversation hypothesis and a variational formulation allow to obtain a dense vector field. The second one is using an affine motion model and a grey level variation hypothesis. An incremental least square ùethod is used to compute the affine parameters. These methods are applied to meteorological infrared images and their results are displayed.Cet article présente et compare deux méthodes d'estimation de mouvement adaptées aux phénomènes météorologiques. La première méthode utilise l'hypothèse de conversation des niveaux de gris et une formulation variationnelle fournit un champ dense de vecteurs tout e...
