Abstract:
1. A method of retrieving an object contained in a domain δ within a space Δ containing a set of objects described in an initial matrix M, comprising a construction of a subset ω of objects contained in the said domain δ by extraction of a matrix μ from the initial matrix M, characterized in that it comprises the following steps: creation of a matrixing M of the space Δ by superimposing a number of geometric matrices with different specifications ρ, representing coverage of the domain by a defined, homogeneous set of similar subdomains, each of the meshes of each geometric matrix being identified by a unique specific numerical value called the matrix code, for the whole of the matrixing M, determination of all the meshes included in domain δ or intersected by domain δ, and the number of relevant objects as the sum of the numbers of objects of the relevant meshes, sorting of matrix M by matrix codes following a predetermined order, increasing or decreasing, of the specifications ρ, and construction of the extraction matrix μ describing just the objects affected by the said meshes included in domain δ or intersected by domain δ.
