摘要
Patterns (f) in a scene (S) are analyzed in order to automatically distinguish symmetrical perceptible areas (P) in the pattern (f), even if said symmetrical perceptible areas (P) are intersected by auxiliary patterns (F). A digitized image (Id) is used, and a test point (cO) located inside the digitized pattern (fd) is used as a starting point. A sequence of circles of increasing diameter is drawn around the test point. Whenever one such circle (CO.sup.i) intersects the digitized pattern (fd) a new center (c1) is chosen, offset from the preceding center (c0) in a direction going away from the point of intersection. By iteration, a sequence of test points (cn) is thus constructed which, for a symmetrical pattern, converges on its center of symmetry (c).
