ABSTRACT:
A method of stabilizing an image sequence, said method comprising the following phases: estimating a first global motion vector comprising a first motion component in a predetermined direction that has associated with it a first respective amplitude and a first respective direction, said first vector being representative of the motion with respect to a reference image of a first image consisting of a pixel matrix, associating said first component with either a wanted motion or an unwanted motion, compensating said first component when it is associated with an unwanted motion, characterized in that the association phase comprises a phase of comparing the first amplitude of said component with a threshold compensation valueTcomphorassigned to the predetermined direction, said first component being associated with an unwanted or wanted motion whenever the first amplitude is, respectively, smaller than said threshold valueTcomphoror greater than/equal to it.
