Abstract: A method of processing uniform mailpieces referred to as a “run” of mailpieces, during which method OCR is performed for recognizing certain information in a zone of interest of an image of each mailpiece, and during which method the following steps are performed: a) initializing a matrix accumulator associated with said run and including unitary accumulation elements that correspond to the pixels of the image; b) consolidating said matrix accumulator by incrementing certain unitary accumulation elements by deriving an indication of the spatial position of a block of pixels in which said certain information has been recognized unambiguously, or by using construction and local graphical correlation of blocks of image pixels to derive an optical flow map indicating local graphical movements; and c) defining, in the OCR processing, said zone of interest on the basis of the unitary accumulation elements of the consolidated matrix accumulator that present extreme accumulation values.

Abstract: The invention relates to a method of optimizing a process for handling mail, which method comprises the following steps: subjecting mailpieces to a first machine-sorting cycle in which a plurality of first sorting outlets are allocated to respective ones of a plurality of first delivery destinations having high rates of filling and one other sorting outlet is allocated to second delivery destinations having low rates of filling; directing separators to the first sorting outlets; re-circulating the mailpieces coming from the other sorting outlet; and subjecting them to a second sorting cycle in which the first sorting outlets are allocated to the second delivery destinations. If the sorting outlets use storage bins, at the end of the second sorting cycle, the mailpieces of a first destination and the mailpieces of a second destination are sorted in layers in the same bin by being separated by a separator.

The invention also relates to a sorting machine including such a device, and to an inspection/monitoring method.

Abstract: In a method of processing mailpieces, signatures are derived from images of the mailpieces and serve as identifiers for the mailpieces in the sorting process. The signatures are grouped together into signature categories or graphical classes on the basis of a certain criterion of graphical similitude so as to compute a mean signature value for each graphical class. For each graphical class in question, activity of the mean signature value is analyzed for detecting significant activity of an information block in the digital images. The results of this activity detection are used for searching for a match, in a second sorting pass, between a current signature and signatures recorded in the first sorting pass.

Abstract: In a method of sorting mailpieces, in which method the mailpieces sorted into the sorting outlets of a postal sorting machine are transferred from said sorting outlets to an unstacker magazine of the machine, or to an unstacker magazine of another sorting machine for the purpose of being sorted again into sorting outlets, said mailpieces are handled by means of shuttle trays of variable storage capacity for the purpose of transferring them from the sorting outlets to the unstacker magazine.

The drive means (20, 30) are distant from each other so as to define the passage zone (40), and the retaining means (24, 34) are suitable for exerting substantially transverse forces in opposite directions, so as to suck at least one article against corresponding drive means. The invention also relates to a method of controlling the above-mentioned separator device (18), and to a postal sorting machine including such a separator device (18).

Abstract: The invention relates to a flat-article feed device, comprising a supply magazine (1) in which flat articles are moved in a stack on edge in a first transfer direction (A), separator means (3) for separating the leading flat article of the stack from the remainder of the stack and for driving it in a second transfer direction (B) that is substantially perpendicular to the first transfer direction, unstacker means (10) that take a flat article that is being unstacked and bring it in said second transfer direction (B) to the inlet of a conveyor, and retaining means (13) that exert a retaining force that opposes movement of the flat article towards the conveyor, said unstacker means being offset from said separator means by a distance not less than the maximum length of a flat article, and said retaining means being provided facing the unstacker means. The invention also relates to a postal sorting machine including such a feed device.

Abstract: A method of processing digital images, in which method a digital image is taken of a mailpiece, which image includes certain information, and certain OCR processing is applied to said image for the purpose of recognizing said information using OCR, the method is characterized in that it further includes a step of applying other OCR processing to said image for the purpose of recognizing said information, and a step of overlaying in said image results of said other OCR processing in a form recognizable by said certain OCR processing. This method makes it possible to obtain reinforced processing capacities by enriching the capacities of the first processing with the capacities of the other processing without calling into question the logical and physical interfaces of the first processing.

Abstract: In a method of processing mailpieces, a digital image of a surface of a current mailpiece is formed for the purpose of using OCR to recognize a recipient postal address for said current mailpiece, and, if it is determined that the recognized recipient address corresponds to an incorrect recipient address, a forwarding address is placed on said surface of the current mailpiece. In addition to said forwarding address, an OCR-detectable mark is placed on the surface of the current mailpiece, which mark indicates that the current mailpiece bears a forwarding address, and also constitutes an index for retrieving said forwarding address from a database.

It further includes a recirculation device for recirculating the mailpieces stored in the sorting outlets, this device comprising a belt (40) mounted to move along the sorting outlets and to which cleats (41, 42) are fastened to define a succession of compartments (4a, 4b, 4c) that face respective ones of the sorting outlets, each compartment being arranged to store, on edge, mailpieces taken from a corresponding sorting outlet.

Abstract: A method of sorting a plurality of articles (A, B, C), in which each article goes through a sorting installation in at least two passes, comprises the steps of recording the image of each article that is generated during the first sorting pass in a memory and in correspondence with a data item indicating a sorting outlet to which the article is directed during the first sorting pass. If an article is misrouted, a correctly routed reference article is chosen in the vicinity of the misrouted article in the sequence of articles obtained during the last sorting pass, the memory is searched (22-28) for an image of said correctly routed reference article, and, on the basis of said reference article image, a set of article images grouped together in the memory and that includes the image of the reference article is looked through (29-34) to identify an image of the misrouted article.
