1. A method for recovering a three dimensional particle system representation of a fuzzy object from a two dimensional image, the method comprising: identifying a fuzzy object in a two-dimensional image; selecting a three-dimensional particle system from a plurality of predetermined three-dimensional particle systems, the particle system relating to a predefined fuzzy object; simulating the particles as a three dimensional image; rendering the simulated particles as a two dimensional image; comparing the rendered two dimensional image to the identified fuzzy object; and wherein if the comparison result is less than a predetermined threshold, accepting the selected three-dimensional particle system to represent a geometry of the identified fuzzy object.
