The present invention relates to a method and a device (100) for hierarchical estimation of motion intended to choose a motion vector (111) from among a plurality of motion vectors for a set of blocks (108) of an origin image (101) divided into blocks. A calculation (102) of an energy function (105) over the set of blocks (108) for each of the motion vectors is carried out. This calculation (102) implements a substep of calculation (103) of a Lagrangian constraint (113) adapted to the size of the set of blocks (108). A choice (107) of a motion vector (111) is carried out by minimizing the energy function (105) over the said set of blocks (108). |
