In S103, judge whether the crown word number information in the multiple crown word number area image is consistent.
In the present embodiment, the mode of judgement is corresponding, according to the different and different of identification crown word number information mode.If
The character information of crown word number is recognized one by one, then the character of crown word number information in multiple crown word number area images is contrasted one by one and sentenced
It is disconnected；If being identified crown word number information as an entirety, then by the multiple crown word numbers in multiple crown word number area images
Information is integrally compared judgement.
In S104, the true and false of the bank note is recognized according to judged result.
In the present embodiment, if the character information included in multiple crown word number area images in S103 is all identical,
Then judge that the bank note is genuine notes；If have in multiple crown word number area images one or more crown word number area image and other
The character information that crown word number image is included is differed, then judge that the bank note is counterfeit money.
Preferably, if judging, the bank note is counterfeit money, and the bank note is positioned over into region to be confirmed.Due to passing through this reality
After applying judgement, the bank note has been determined as counterfeit money, it is therefore desirable to carry out difference placement with genuine notes, in case a large amount of bank note are identified
After operation, counterfeit money is still mixed into the middle of genuine notes.
Whether the embodiment of the present invention passes through to judge the consistent true and false to recognize bank note of information of multiple crown word numbers, because illegal
Molecule, due to the imperfection and the relation of a large amount of photocopy of urgent need of technology, is printing crown word number mistake during counterfeit money is manufactured

Fig. 2 shows a kind of flow chart of the recognition methods of forge or true or paper money that another embodiment of the present invention is provided.Referring to Fig. 2
Shown, a kind of recognition methods of the forge or true or paper money provided relative to a upper embodiment, the present embodiment is relative in a upper embodiment
Crown word number information in the multiple crown word number area image of identification has made further restriction, and details are as follows：
In S205, the multiple crown word number area image is divided into multiple character respectively according to default segmentation strategy
Image, each character subgraph includes a character information.
In the present embodiment, for the ease of the character recognition in later stage, the character picture that will be included in crown word number area image,
It is unit according to character, is divided into character subgraph independent one by one.The storage order of character subgraph after segmentation, according to word
Order in symbol frame region, from left to right, is from top to bottom stored in register successively.Character subgraph after segmentation
Represent a corresponding character.
In the present embodiment, segmentation strategy refers specifically to the method by picture segmentation according to matching algorithm.Illustratively,
In the present embodiment, by detecting that each pixel point value of continuous two row is identical or difference of pixel point value is less than predetermined threshold value, then
Judge to need segmentation at this.
In S206, the multiple characters included in multiple character subgraphs of each crown word number area image are recognized respectively
Information, and the crown word number information according to corresponding to the multiple character information generates the crown word number area image.
Preferably, in the present embodiment, the method for identification character information is the template by character subgraph and specification character
Compare, the minimum template of selection differences as character subgraph matching template, the corresponding character of matching template is this
Character represented by character subgraph.
In the present embodiment, the corresponding crown word number information of the crown word number area image is generated to come specifically, will identify that
Character information, carry out rearrangement combination in the order of crown word number area image according to the character subgraph before segmentation, obtain
Unique crown word number information sequence.
In embodiments of the present invention, single character recognition is carried out by segmentation, so as to reduce the operand of identification character, is carried
The efficiency of truth identification high.In the case of for a multiple character mixing in one image, identification is needed by a large amount of
Permutation and combination scheme compare identification, this will increase the recognition time of computer, and know because multiple characters mix
The interference between image character can not be produced, so as to lower the accuracy rate of identification.And single character separately recognize will solve it is above-mentioned
Problem.
Further, as an alternative embodiment of the invention, the recognition methods of the forge or true or paper money also includes：
In S201, the character sample image that multiple includes identical characters, the multiple character sample image point are obtained
Wei Yu not be in multiple currency types, face amount identical bank note in the crown word number area image of same position.
In the present embodiment, it is used as the template of character subgraph matching, it is necessary at such to obtain enough samples
In type bank note, substantial amounts of sample image is gathered, and the sample image for being gathered should belong to positioned at same crown word number area image
It is interior.For different characteristic images, even if representing same character, because font and the relation of stretcher strain, can influence the hat
The pixel distribution of character subgraph in font size area image.Therefore, in collecting sample, corresponding to the pixel of same character
The sample of characteristic value template, should also be located in the crown word number area image of same position.
In the present embodiment, sample image quantity should be greater than 100.Substantial amounts of sample image quantity is gathered, can be caused
Template is more representative, overcomes the error produced because of the influence of noise or shooting machine.
In S202, the mean pixel point value that the multiple character sample image is often gone is used as the preset configuration list
Corresponding row pixel point value in the pixel characteristic value template of the middle correspondence character；By the multiple character sample image each column
Mean pixel point value is arranged accordingly as the pixel characteristic value template of the correspondence character in the preset configuration list
Pixel point value.
In the present embodiment, each column in pixel characteristic value template often row pixel point value by sample mean pixel point value structure
Into.Multiple sample images are acquired in S201 steps, the pixel point value of corresponding row are added again divided by sample size, you can
Obtain mean pixel point value.Especially, for binary image, because should only there are 0 or 255 two values in sample image, because
This, when pixel point value is averaging, should choose 127 and be not more than 127 as benchmark value, i.e. the mean pixel point value, then sentence
The pixel point value of breaking is 0；Conversely, then judging that the pixel point value is 255.
In S203, the pixel characteristic value template of the correspondence character is stored in preset configuration list.
In embodiments of the present invention, sample form is used as by the image in actual banknote, relative to being stored in computer
In standard letter Character mother plate for, it is more close with character subgraph to be judged.Therefore, it is possible to improve identification character
Accuracy rate, and then improve the accuracy rate of forge or true or paper money identification.
It should be noted that in the present embodiment S204 and S207 due to embodiment illustrated in fig. 1 in S101 and
It is identical that S104 implements process, therefore repeats no more in this embodiment.
Further, as an alternative embodiment of the invention, relative to a upper embodiment, Fig. 3 shows segmentation strategy
Specific steps, the segmentation strategy is specially：
In S301, the default screens matched with the crown word number area image is chosen by template matching algorithm and is cut
Template.
In the present embodiment, the different default screens cutting board of different crown word number area image correspondences, due to font
And the reason for image stretch, the elemental area shared by each character is also different, therefore, for different crown word number administrative division maps
Picture, distributes different default screens cutting boards.
In the present embodiment, because crown word number is that a line is sequentially arranged, therefore row line of cut can be first chosen, by crown word number area
Area image is by character for unit cuts apart successively.If character information described in the crown word number area image is not horizontally arranged,
The crown word number area image then carries out rotation process is horizontally arranged to character, then carries out above-mentioned cutting operation.
In S302, the crown word number area image is cut into multiple words using the default screens cutting board for matching
Symbol subgraph.
In the present embodiment, by recognizing the border of character, cutting operation is being carried out using default screens cutting board.Lift
Example property ground, the crown word number area image is binary image, pixel point value detection is carried out to the subgraph from left to right, when first
The secondary subgraph pixel point value that includes of row that detects is 0 pixel, then judge that this is classified as the left margin of a character subgraph；
When being consecutively detected, the subgraph is a few to arrange the pixel that the pixel point value that does not include is 0, then judge that this is classified as a character subgraph
The right margin of picture.Up-and-down boundary is determined by this detection method, so that it is determined that going out all characters in the crown word number area image
The character boundary of subgraph, cutting board is then applied mechanically again carries out cutting operation.
In implementation is invented, by using identical form and size, character subgraph is intercepted, character subgraph can be easy to
Storage and identification, so as to improve the accuracy rate of forge or true or paper money identification.
Further, referring to Fig. 4, as an alternative embodiment of the invention, relative to the embodiment shown in Fig. 2, this reality
Example is applied to do the multiple character informations included in the multiple character subgraphs for recognizing each crown word number area image respectively
Further refinement, details are as follows：
Multiple character informations included in the multiple character subgraphs for recognizing each crown word number area image respectively
Specially：
In S401, by often row pixel point value and each column pixel point value in the multiple character subgraph, respectively with advance
If the corresponding row pixel point value of pixel characteristic value template and row pixel point value in configured list carry out differing from square operation, obtain
Multiple difference square value, the pixel characteristic value template one specific character of correspondence in the preset configuration list.
In the present embodiment, because character subgraph is stored in a digital format, therefore character subgraph is considered as one
The individual image being made up of multiple pixel grid points, the character subgraph each column or row has several pixels, the pixel
Point has pixel point value, for colored image, the pixel point value is constituted by tri- pixel values of RGB；For gray level image, then by
The gray value of the point as the point pixel point value；For binary image, then the pixel point value of the point is 0 or 255.
In the present embodiment, the pixel characteristic value template at least two in preset configuration list, it is preferable that preset configuration
At least 36 pixel characteristic value templates in list, comprising corresponding to 26 templates and 10 numeric words of upper case alphabetic character
The template of symbol.
Preferably, in the present embodiment, each one described preset configuration list of the crown word number area image correspondence, institute
The character subgraph stated in characteristic image is compared with the template in corresponding preset configuration list.Due to for different spies
Levy image, identical character may be printed with different fonts or stretcher strain is caused and had any different in display through typesetting,
Therefore be conducive to improving the accuracy of matching using different lists.
In S402, the multiple poor square value summation is stated the matching numerical value of template as institute's pixel characteristic value.
Illustratively, character subgraph is binary image, and picture traverse and height are 3 pixels, specific pixel
Point value is distributed as：The pixel point value of a wherein pixel characteristic value template is distributed as：Then the first row pixel point value of the character subgraph is 255+255+0=510, the pixel characteristic value
The pixel point value of template the first row is 255+0+0=255, then both differences square are (510-255)2=65025.Remaining each row
Each leu time is calculated, the matching numerical value of the poor square value sum for the drawing as pixel characteristic value template.
In S403, in the multiple pixel characteristic value template, a minimum picture of the matching numerical value is obtained
Plain characteristic value template, using the specific character corresponding to the minimum pixel characteristic value template of the matching numerical value as the word
The corresponding character of symbol subgraph.
In the present embodiment, because by image, after differing from square operation, the matching value for obtaining can effectively represent multiple
Matching degree between image, therefore, the minimum corresponding pixel characteristic value template of selection matching numerical value, it is believed that the template be with
The most close pixel characteristic value template in preset configuration list of the character subgraph.
Preferably, if the character pixel template corresponding to matching numerical value minimum has multiple, using identification strategy selection
Optimum Matching template, the identification strategy is specially：Judge whether the matching value identical multiple pixel characteristic value template belongs to
In same big class template, if so, then using character feature diagnostic method；If it is not, then using center convergence diagnostic method.
In the present embodiment, same big class template is referred to corresponding to the pixel characteristic value template in preset configuration list
Character shape it is close, illustratively, character " 6 " and character " 9 "；Character " 0 ", character " O " and character " D " etc..This
In the case of, we can further be screened using feature decision method to pixel characteristic value template.Illustratively, for word
Symbol " 6 " and character " 9 ", can detect the area pixel point Distribution value in the character subgraph upper right corner, if only a small amount of in the region
Point value is 0 pixel, then judge that the corresponding character of character subgraph is " 6 "；Conversely, then corresponding character is " 9 ", remaining
Each major class character also can carry out further refinement and differentiate by the method for same feature decision.
In the present embodiment, center convergence diagnostic method refer to reduce borderline region differentiation, that is, leave out first trip first with
And footline terminal column, then carry out differing from square matches method.Due to the multiple pixel characteristic value templates for being not belonging to same major class
Matching numerical value is identical, it may be possible to caused because the noise on border is more；On the other hand, when two characters be not belonging to it is same big
Class, closer to picture centre, its difference will be bigger, therefore, can be judged using the method for gradually decreasing border to compare.
In embodiments of the present invention, the minimum matching template of difference is selected by difference square matches method and is used as the character subgraph
The corresponding templates of picture, so as to recognize the character that character subgraph is represented.The method is realized simply, by simple poor square of fortune
Calculate, you can identification image character, the time of forge or true or paper money identification is improve, so as to improve recognition efficiency.
It should be understood that the size of the sequence number of each step is not meant to the priority of execution sequence, each process in above-described embodiment
Execution sequence should determine that the implementation process without tackling the embodiment of the present invention constitutes any limit with its function and internal logic
It is fixed.
