Definitions

  • BSA automatic letter sorting systems
  • the BSA will manage it appropriate mailing in the reject compartment. This has increased processing costs and lengthened Processing times result, since the addresses of these shipments in the reject compartment below must be entered manually.
  • the address block marking is set manually, which is also possible, but after Processing of the mailing by mistake is not deactivated, so in subsequent mailings, that no longer belong to the corresponding mailing, usually on the wrong one Searched for the address block. This also leads to unnecessary rejection of shipments and the resulting adverse consequences.
  • the read rates of the BSA are thus avoidably lower than if the address block on the Envelope would have been located correctly automatically.
  • This task is accomplished by a method for automatic address block marking of Shipments in letter sorting systems solved, the address block automatically recognized and is marked for further processing of the address and characterized according to the invention is that the address block by forming images of two on top of each other following programs is recognized.
  • the method or the letter sorting system, as outlined here, are used for automatic Address block marking at the BSA with minimal additional effort. Through this procedure according to the present invention or this BSA according to the invention are eliminated previously disadvantages mentioned largely.
  • the penultimate letter as a reference for a subsequent one, preferably for the last one - that is to say current considered - it is possible to find an offset for a mailing without referring to a letter Database of stored images.
  • significant cost advantages can also be expected. Additionally influenced this approach the robustness of the procedure positive.
  • a preferred embodiment of the method for automatic Address block marking of mail items in letter sorting systems is characterized by that an identifiable by means of image recognition and of its geometric outlines ge locally determinable area with, preferably above a residual threshold, remaining Remaining patterns after forming the difference between the images of the two successive images Shipments are automatically recognized as an address block.
  • the address field area can be determined locally a residual pattern remaining after the difference has been formed.
  • the process for automatic address block marking of mail items in letter sorting systems according to the present invention is preferably also designed to be based the difference image of two consecutive programs is decided whether the the following program belongs to the same mailing as the previous program, what can easily happen, for example, by adding up the amplitudes of the difference image matrix and compared with a threshold. If the threshold is exceeded, the difference is too high and the two images compared do not belong to one Mailing. If, on the other hand, the threshold is undershot or only reached, they are part of the same mailing. When determining the threshold value, it makes sense to take into account what values typically result when you look at the amplitudes of the individual pixels of the address field, since this is the variable within the same mailing represents.
  • the images B A and B M after step b) and before step c) can each be aligned in such a way that the highest possible congruence between them is achieved, which is conducive to the difference image determination, it being noted that this congruence alignment for everyone in the Differential image determinations addressed within the scope of the present invention comes into question.
  • the one recognized by the method according to the invention is preferably recognized automatically Address block marked in that around it one, preferably in size for Suitable addressing, rectangle is placed.
  • key figures are determined for the comparison pattern B M used in each case as reference, which based on a few criteria allow a probability statement as to whether the letter currently being viewed B A belongs to the same mailing as B M.
  • the following key figures are used, for example: the number of different colors or grayscale, a histogram of the color / grayscale distribution, the proportion of unprinted area as well as mean values, quantiles and ranges for brightness and contrast properties.
  • these key figures can be determined on a restricted partial letter image or on the overall letter image.
  • an area must be selected and specified for the mailing that lies outside the suspected address block area and differs as much as possible from monochrome (including unprinted areas).
  • the franking area should not be used as a partial letter for the determination of these key figures.
  • the current address block marking belonging to B M is stored.
  • a new identification of the address block can then be dispensed with and the stored address block position can be adopted, or specifically in a slightly expanded area around the stored address block position after current address block are searched, or the evaluation can be carried out without using a stored address block position.
  • An embodiment of the method according to the invention is therefore also used for automatic Address block marking of mail items in letter sorting systems preferred in the case of the basis of a key figure comparison of the key figures of the respective picture between the previous shipment serving as a reference and a respective one currently viewed following program by way of a probability assessment a decision is made as to whether the subsequent consignment viewed in each case belongs to the same mailing belongs like the previous broadcast, which serves as a reference.
  • a partial image area of the image of the mail items can be used for the determination the key figure or key figures are used, preferably as a partial image area an area is selected that is outside the presumed address block area lies and which, including the unprinted areas, is as little as possible monochrome and which is preferably also outside the franking area.
  • images B A and B M after step b) and before step c) can each be aligned in such a way that the highest possible congruence between them is achieved, which - as already discussed - is conducive to determining the difference image, although here too It should be noted once that this congruence alignment can be used for all differential image determinations addressed in the context of the present invention.
  • the automatic marking of the address of a mailing is preferably also used for the subsequent mailings assigned to the same mailing.
  • B A belongs to the same mailing as picture B M
  • it is preferable afterwards to dispense with a new automatic address block search and marking by means of differential picture creation and the address block marking which has already been saved can be adopted for the mailing with picture B A.
  • the address of a subsequent mailing of the same mailing can also be targeted in one slightly expanded area searched for the already existing automatic marking become.
  • this extended image memory can be designed as a temporary memory for a small number of different images or as a permanent image database.
  • the inventive method for automatic address block marking of mail items in letter sorting systems preferably also be designed so that in the event that it is decided that the subsequent program does not belong to the same mailing as the previous broadcast, a comparison of the respective ones subsequent program with comparison samples in an expanded image memory is carried out, the expanded image memory including such comparison patterns Address block position and / or any key figures or key figures available from already evaluated images come from mailings, based on which the identification of a new shipment from the respective deposited mailing and the corresponding one automatic address block marking takes place.
  • a manual address block marking option is preferred provided that also a storage of the image with a manual marked address block in the expanded image memory as a comparison pattern.
  • the present one described above can be described more in terms of procedure Invention of course also as a device, for example in the context of a letter sorting system with appropriate control, the difference from the recorded letter images determined - which is not necessarily - but preferably using a computer happens -, and then the typical pattern of the address block searched for, preferably typical structure, for example based on a degree of similarity to a comparison pattern, recognizes.
  • 1 shows the basic structure of a letter sorting system 6 and the problem of rejecting letters 0a , 0b that occurs because the address block 4 is not recognized .
  • Mail items 0a, 0b specifically letters from mailings with extensive advertising imprints 0a and also letters 0b , which do not originate from such mailings, reach a letter sorting system 6 , which has a control 6a , for example a computer with a memory, which contains the address block 4 of the respective letters 0a , 0b should be automatically recognized and marked by means of an address block marker 5 , preferably in the memory of the computer, so that the address can then be read automatically. If this succeeds, so an automatic address block marking 5 can take place, the letter 0b leaves the letter sorting system 6 in the normal way 7 for further processing.
  • a control 6a for example a computer with a memory, which contains the address block 4 of the respective letters 0a , 0b should be automatically recognized and marked by means of an address block marker 5 , preferably in the memory of the computer, so that the address can then be read automatically. If this succeeds, so an automatic address block marking 5 can take place, the letter 0b leaves the letter sort
  • the address block 4 is automatically recognized here and marked 5 for further processing of the address, this being done in such a way that the address block 4 is recognized by forming images BM , BA of two consecutive programs.
  • images BM , BA of two consecutive programs preferably an identifiable by means of image recognition and geometric by its outlines forth locally determinable area with, preferably automatically detected above a Restschwell learners, remaining residual pattern 4a by subtraction of the images BM, BA of the two consecutive broadcasts as the address block 4a and by means of a Adreßblockmark ist 5, here a Rectangle, marked in the difference image BD .
  • the disturbing elements which are almost always the same, such as sender details 2 , advertising imprints 3a, 3e logos 3b, 3c, 3d, but also the franking area 1 with the postage stamp outside the address block 4 - Blended away (at least up to a residual threshold value), which then enables the identification of the address block 4 , where this blending does not work due to the different addresses, and as a result an address field area that can be identified by means of image recognition and that can be determined spatially based on its geometric outlines, with an after difference formation remaining residual pattern 4a for marking 5 remains in the difference image BD .
  • FIG. 3 shows an unsuccessful automatic address block marking based on a difference image determination.
  • the address block 4 cannot be automatically recognized here based on the difference image determination and marked for further processing of the address, since the difference image BD due to the difference in the images BM, BA of the two consecutive programs not only one now due to the different position of the address block 4 in the images BM and BA shows extended residual pattern address block 4a , but also residual patterns in the sender area 2a , residual patterns in the franking area 1a (since different postage stamps may have been used here) and negative residual patterns 3aa, 3ba, 3ca in advertising or logo printing areas.
  • an automatic Adreßblockerkennung and thus mark 5 and accordingly no such Adreßblockmark ist 5 are first saved.
