A segmentation procedure based on characteristics, for segmenting a plurality of articles (3) duplicates arranged in a disorderly manner, characterized by comprising the steps of: a) acquiring an image (M) of an article (30) of sample; b) calculating the significant points of the image (M) of an article (30) and descriptorescorrespondientes sample in order to obtain a respective plurality of descriptor significant point-pairs (a1 ... a13) image (M) of an article (30) of sample; c) defining a figure (Z) identifying image of an article (30) of sample to approximate Article unaforma (30) illustrated sample image (M) of an article (30) of sample; d) acquiring a first image (I1) of a plurality of duplicate articles; e) calculating the significant points of the first image (I1) of the plurality of items (3) and losdescriptores corresponding duplicate in order to obtain a respective plurality of pairs significativodescriptor point (b1 ... b17) of the first image ( I1) of the plurality of articles (3) duplicates; f) determining a matching descriptor pairs significant-point (a1, ... a13) image (M) of unartículo (30) shows the significant point-descriptor (b1 ... b17) of the first pairs image (I1) of unapluralidad of articles (3) duplicate in order to define correspondences of similarity between the descriptor-puntosignificativo (a1 ... a13) image (M) of an article (30) and sample pairs the puntosignificativo-descriptor pairs (b1, ..., b17) of the first image (I1) of a plurality of articles (3) duplicates; g) recognize a relative position and an identification relative orientation of the figure (Z) with respect to unprimer pair significant-descriptor point (a10) of the image (M) of an article (30) of sample having unacorrespondencia with a second pair significant point-descriptor (b13) of the first image (I1) of unapluralidad of articles (3) duplicates; h) defining, in the first image (I1) of a plurality of articles (3) duplicate, a figure of proyecciónidentificativa (Z6) having a shape and a size that are comparable or identical to the figuraidentificativa (Z), whose figure identification projection (Z6) has a relative position and a orientaciónrelativa with respect to the second point pair significant-descriptor (b13) of the first image (I1) of unapluralidad of articles (3) duplicates are identical, respectively, to position relative and orientaciónrelativa assumed by the identifying figure (Z) disposed on the image (M) of an article (30) conrespecto shows the first point pair significant-descriptor (a10) of the image (M) of an article (30) sample; i) applying the two preceding steps to a plurality of significant-descriptor point (a2, a1, a5, a3, a4, a10, a11, a8, a9) pairs image (M) of an article (30) It samples having a correspondence with a p arpunto significant-descriptor (b12, b7, b9, b5, b4, b13, b10, b2, b11) of the first image (I1) of a plurality deartículos (3) duplicates; j) collecting the figures of identification projection (Z1, ..., Z9) having therebetween one gradopredeterminado overlay; k) defining a representative (F1, G1) is contained for each group of figures identifying projection (Z1, ..., Z9) which is formed by a predetermined projection figures identifying (Z1, minimum ..., Z9) whose representative figure (F1, G1) it has a shape and dimension that a figure of proyecciónidentificativa (Z1, ..., Z9), and is selected in order to estimate a position of an article (3) in the first correspondienteilustrado image (I1) of a plurality of articles (3) duplicates.
