1. Method of locating addresses on articles to be sorted in order to enable scanning of said addresses, said method comprising:
- associating with each address an addressing mark different from all other information likely to be carried by said articles, said mark comprising a first part whose shape is invariant on rotation and a second part having an irregular shape;
producing a digitized image of each article;
determining within said image two cartesian coordinates of a point on said first part of said mark in order to deduce therefrom two cartesian coordinates of a point of the address to be scanned, by comparing at least part of said digitized image to a first predetermined data set characteristic of said first part of said mark;
determining the orientation of said second part of said mark in said image, in order to deduce therefrom the orientation of said address to be scanned, by comparing at least one part of said digitized image with a second predetermined data set characteristic of said second part of said mark oriented in a plurality of different directions.

Abstract
In a method of locating addresses on articles to be sorted, such as mail items of many different kinds, a specific addressing mark is associated with the address on an addressing label or other addressing support. The mark comprises a ring and an asymmetric logotype.

3. Address label adapted to carry an address and, associated with said address, an addressing mark comprising a first part whose shape is invariant on rotation and a second part whose shape is irregular, so that an address on said label on articles to be sorted can be located by a method comprising:
-
producing a digitized image of each article; determining within said image two cartesian coordinates of a point on said first part of said mark in order to deduce therefrom two cartesian coordinates of a point of the address to be scanned, by comparing at least part of said digitized image to a first predetermined data set characteristic of said first part of said mark; determining the orientation of said second part of said mark in said image, in order to deduce therefrom the orientation of said address to be scanned, by comparing at least one part of said digitized image with a second predetermined data set characteristic of said second part of said mark oriented in a plurality of different directions. - View Dependent Claims (4, 5)

6. Device for locating addresses on articles to be sorted in order to enable scanning of said addresses, by a method comprising:
-
associating with each address an addressing mark different from all other information likely to be carried by said articles, said mark comprising a first part whose shape is invariant on rotation and a second part having an irregular shape; producing a digitized image of each article; determining within said image two cartesian coordinates of a point on said first part of said mark in order to deduce therefrom two cartesian coordinates of a point of the address to be scanned, by comparing at least part of said digitized image to a first predetermined data set characteristic of said part of said mark; determining the orientation of said second part of said mark in said image, in order to deduce therefrom the orientation of said address to be scanned, by comparing at least one part of said digitized image with a second predetermined data set characteristic of said second part of said mark oriented in a plurality of different directions, said addressing mark combining a ring having specific inside and outside diameters and an irregular shape insignia associated with said ring, and said device comprising; means for detecting pairs of opposite segments of said ring in said digitized image of each article from said first data set defining said characteristics of said ring, means for processing pairs of detected opposite segments to determine a ring center, means for extracting the image from the interior of said ring corresponding to each identified center in said digitized image of said article, and means for comparing said image extracted from said interior of said ring with a limited number of reference images representing said second data set, confirming or validating said center and said ring and defining the orientation of said addressing mark and therefore the position of said address when a single coincidence is detected by said comparison for all of said image of said article. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
