Patent ID: 7151845

Claim:
A method for gradually deforming an initial realization formed from measurements or observations and defining a distribution of a set of objects in a zone of a heterogeneous medium, generated by simulation of an object type stochastic model, the objects being distributed in the zone according to a Poisson point process in a form of figurative points with a point density λ(x) varying according to their position (x) in the zone, comprising: generating a realization of a uniform random vector according to which a position of each object is defined while respecting density λ(x); and gradually modifying the uniform random vector according to a gradual deformation procedure, so as to obtain gradual migration of each object and consequently gradual change in the distribution of the objects in the zone, until a final realization best adjusted to parameters relative to the structure of the medium, is obtained, which gives a realistic representation of the configuration of the objects in the modelled heterogeneous medium.
