Abstract

In a process for detecting target patterns in a texture with which a system state can be represented as a distribution of points in an n-dimensional space, anisotropic scaling factors a.sub.ji are determined which are characteristic of the relationship between the projection of the point density onto coordinate j and the distance to examined point P.sub.i. A target is detected if the distribution of scaling factors deviates from predetermined comparison distributions of systems without target patterns.
