摘要：
The present invention relates to a method and a device for hierarchical estimation of motion intended to choose a motion vector from among a plurality of motion vectors for a set of blocks of an origin image divided into blocks. A calculation of an energy function over the set of blocks for each of the motion vectors is carried out. This calculation implements a substep of size of calculation of a Lagrangian constraint adapted to the size of the set of blocks. A choice of a motion vector is carried out by minimizing the energy function over the said set of blocks.
