A method for estimating the motion of regions (R) of any shape in a digital image (I?1?) in relation to a different digital image (I?2?). A motion model (Â) is calculated using an algorithm that calculates coefficients of a bivariate polynomial describing the motion of the region (R). The model is identified by minimising an error criterion for the reconstruction of the region (R), by means of a non-linear local programming technique and a multiresolution image analysis enabling a global optimum to be achieved. |
