1. A method for estimation of motion in a series of images captured by an image sensor where said series of images comprises at least one preceding image I k-1 and one following image I k and the images comprise points with which are associated brightness data: where said method comprises estimating the estimated motion vectors, done at a plurality of image points chosen among the list made up by the previous image I k-1 and the following image I k ; where for each of the points of said plurality of points of an image, an operation of minimization of a functional of motion vectors; where the functional comprises a sum of at least one data term and one regulation term; where the data term is a function of spatial-temporal gradients of brightness data associated with a plurality of points from a neighborhood of a point; where the regulation term has at least one finite value for each of the points of said plurality of points of an image in the area of which the minimization of the data term provides an irregular solution; said data term comprises a product of a weighting term and a data linkage term; where the weighting term is a function of the degree of regularity of the estimated motion vectors; where the data linkage term is a function of spatial-temporal gradients of brightness data associated with a plurality of points from a neighborhood of a point.
