摘要： The invention relates to a method of encoding and decoding video images with spatial scalability. The inventive method comprises the following steps consisting in: encoding (5) a low-resolution image, by performing a calculation of a local or reconstructed decoded image, in order to supply an encoded low-resolution image; oversampling (6) the reconstructed image in order to supply a prediction image; and encoding (7) a higher resolution image, comprising a difference calculation with the prediction image in order to supply residues. The invention is characterised in that the method also comprises a step consisting in selecting or calculating filter coefficients to be used for oversampling and a subsequent step consisting in encoding said coefficients such that they can be transmitted to the decoder with the other encoded data. The invention is suitable for hierarchical encoding with spatial scalability.

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.
