In two-dimensional model based image coding, an image is partitioned into domains, and the pixels of each domain are modeled with a polynomial intensity function. An image coded in this fashion is comprised of a description of the domain boundaries and individual descriptions of polynomial intensity...http://www.google.fr/patents/US5917953?utm_source=gb-gplus-shareBrevet US5917953 - Geometry implicit sampler for polynomial surfaces over freeform two-dimensional domains
