1. A method of representing motion in a sequence of digitized images comprising generating and coding a plurality of versions of a motion vector field at different resolutions, comprising the steps of:

  • producing a motion vector field at a first, coarse, resolution and at a second, finer, resolution;

    up-sampling the coarse resolution version of the motion vector field;

    comparing the up-sampled coarse resolution version of the motion vector field with the finer resolution version of the motion vector field;

    coding the coarse resolution version of the motion vector field; and

    coding the finer resolution version of the motion vector field on the basis of the results of the comparison.
