Abstract
A method for estimation of motion in a series of images captured by an image sensor comprising an estimation of motion vectors at a plurality of points from an image by an operation, done at each of the points from the plurality of points, of minimization of a functional of motion vectors comprising the sum of a data term and a regulation term, where the data term is made up of the product of a weighting term which is a function of the degree of regularity of the estimated motion vectors and a data linkage term which is a function of the spatial-temporal gradients of the brightness near points located in a neighborhood of a point, where the regulation term supplies a result to the minimization operation for the points near which the minimization of the data term does not allow estimating a unique solution.
