                         isocontours from regular and irregular 2D sampled data and to 
                         encode it at single rate or progressively. A dynamic tessellation 
                         is used to represent and adapt the 2D data to the isocontour. This 
                         adaptation induces a controlled multi­resolution representation of 
                         the isocontour. We can then encode this representation and control 
                         the geometry and topology of the decoded isocontour. The resulting 
                         algorithms form an efficient and flexible isocontour extraction 
                         and compression scheme.",
