Claim One:
1. A method for the estimation of motion in a series of images captured by an image sensor, said series of images including at least one preceding image and one following image; said estimation method including the following steps: /a/ obtaining a first estimated motion by carrying out a global motion estimation from the preceding image to the following image; /b/ obtaining a compensated image based on the first estimated motion, from either one of the preceding and following images; /c/ obtaining a second estimated motion by carrying out a dense motion estimation between the compensated image and the other one from the preceding and following images; /d/ determining a global motion residual value; and /e/ if the residual value is less than a threshold value providing the second estimated motion, otherwise repeating steps /a/-/e/; in which the first estimated motion is determined by applying a binary image mask; and in which, if in step /e/ the steps /a/ to /e/ are repeated, they are carried out by applying a binary image mask updated as a function of the second estimated motion.
