Elliptic diagrams: application to patterns detection from a finite set of points
The novelty of this paper is the selection of a family of affine diagrams, for which we show their adequate properties in detecting regular sampled patterns (structures) embedded in a noisy background. The technique of detecting the structures from a finite set of points is done through an extension of the ?-shape concept, we name, elliptic ?-shape.
