1. Method comprising encoding of a mesh representing an image of a moving sequence, wherein said mesh is larger in size than said image, and associating at least one of the following markers with at least certain of the vertices and/or certain of the faces of said mesh:

  • an “

    internal”

    marker,one face carrying an “

    internal”

    marker if it has a non-vacant intersection with said image,and one vertex carrying an “

    internal”

    marker if it belongs to an “

    internal”

    face;

    an “

    entering”

    marker,one vertex carrying an “

    entering”

    marker if it carries an “

    internal”

    marker and if it is external to the image,and one face carrying an “

    entering”

    marker if at least one of the three vertices that it connects carries an “

    entering”
