Crown word number can also be identified as a whole, extract the information image of crown word number.
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 correspondingly, different according to the difference of identification crown word number information mode.If
The character information for identifying crown word number one by one, then compare one by one by the character of crown word number information in multiple crown word number area images and sentence
It is disconnected；If crown word number information is identified as a whole, then by multiple crown word numbers in multiple crown word number area images
Judgement is integrally compared in information.
In S104, the true and false of the bank note is identified according to judging result.
In the present embodiment, if the character information for including in multiple crown word number area images in S103 is all identical,
Then determine the bank note for 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 includes is not identical, then judges the bank note for counterfeit money.
Preferably, if judging the bank note for counterfeit money, the bank note is placed in 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 difference placement is carried out with genuine notes, in case a large amount of bank note are identified
After operation, counterfeit money is still mixed into genuine notes.
The embodiment of the present invention is by judging whether the information of multiple crown word numbers is consistent, to identify the true and false of bank note, because illegal
Molecule is during manufacturing counterfeit money, due to the not perfect of technology and the relationship of a large amount of photocopy of urgent need, in printing crown word number mistake
Cheng Zhong, the case where often will appear wrongly typed, bite.And the legal bank note of country's distribution due to technology maturation and has Special Survey
Department is not in such case.Therefore, the forge or true or paper money identification that the embodiment of the present invention is realized, does not need manually to carry out
The differentiation of the true and false is not relying on the image that purple light projection post analysis shows also to determine forge or true or paper money, improves forge or true or paper money mirror
Other recognition efficiency also reduces the cost of forge or true or paper money identification.
Fig. 2 shows another embodiment of the present invention provides a kind of forge or true or paper money recognition methods flow chart.Referring to fig. 2
Shown, relative to a upper embodiment, a kind of recognition methods of forge or true or paper money provided in this 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 include a character information.
In the present embodiment, for the ease of the character recognition in later period, the character picture that will include in crown word number area image,
It is unit according to character, is divided into independent character subgraph one by one.The storage order of character subgraph after segmentation, according to word
The sequence in information image region is accorded with, from left to right, is from top to bottom successively stored in registers.Character subgraph after segmentation
Indicate a corresponding character.
In the present embodiment, segmentation strategy refers specifically to the method according to matching algorithm by picture segmentation.Illustratively,
In the present embodiment, each pixel point value of continuous two column is identical or the difference of pixel point value is less than preset threshold by detecting, then
Judge to need to divide at this.
In S206, multiple characters included in multiple character subgraphs of each crown word number area image are identified respectively
Information, and according to the multiple character information generate the crown word number area image corresponding to crown word number information.
Preferably, in the present embodiment, the method for identifying character information is by the template of character subgraph and specification character
It is compared, matching template of the smallest template of selection differences as character subgraph, the corresponding character of matching template is should
Character represented by character subgraph.
In the present embodiment, it generates the corresponding crown word number information of the crown word number area image and comes specifically, will identify that
Character information, carry out rearrangement combination in the sequence 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, to reduce the operand of identification character, mentioned
The efficiency of high truth identification.The case where due to characters multiple for one mixing in one image, identification is needed by a large amount of
Permutation and combination scheme identification is compared, this will will increase the recognition time of computer, and know since multiple characters mix
The interference between image character can not be generated, to lower the accuracy rate of identification.And single character separately identify will solve it is above-mentioned
Problem.
Further, as another embodiment of the invention, the recognition methods of the forge or true or paper money further include:
In S201, obtain it is multiple include identical characters character sample image, the multiple character sample image point
Not Wei Yu multiple currency types, in the identical bank note of face amount in the crown word number area image of same position.
In the present embodiment, it in order to obtain enough samples as the matched template of character subgraph, needs at such
In type bank note, a large amount of sample image is acquired, and sample image collected should belong to positioned at the same crown word number area image
It is interior.For different characteristic images, even if indicating same character, because font and the relationship of stretcher strain, will affect the hat
The pixel distribution of character subgraph in font size area image.Therefore, the pixel in collecting sample, corresponding to the 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.A large amount of sample image quantity is acquired, can be made
Template is more representative, overcomes the error generated because of the influence of noise or shooting machine.
In S202, using the mean pixel point value of the multiple every row of character sample image 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 arranges accordingly as the pixel characteristic value template of the correspondence character in the preset configuration list
Pixel point value.
In the present embodiment, the every row pixel point value of each column in pixel characteristic value template by sample mean pixel point value structure
At.Multiple sample images are acquired in S201 step, and the pixel point value of corresponding row is added again divided by sample size
Obtain mean pixel point value.Particularly, for binary image, since sample image should only have 0 or 255 two values, because
This should choose 127 and be used as benchmark value, is i.e. the mean pixel point value is not more than 127, then sentences when being averaging pixel point value
The pixel point value of breaking is 0；Conversely, then judging the pixel point value for 255.
In S203, the pixel characteristic value template of the correspondence character is stored in preset configuration list.
In embodiments of the present invention, by the image in actual banknote as sample form, 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 can be improved 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 in embodiment illustrated in fig. 1 S101 and
It is identical that S104 implements process, therefore repeats no more in this embodiment.
Further, as another embodiment of the invention, relative to a upper embodiment, Fig. 3 shows segmentation strategy
Specific steps, the segmentation strategy specifically:
In S301, the default detent to match with the crown word number area image is chosen by template matching algorithm and is cut
Template.
In the present embodiment, different crown word number area images corresponds to different default detent cutting boards, due to font
And the reason of image stretch, elemental area shared by each character is also different, therefore, for different crown word number administrative division maps
Picture distributes different default detent cutting boards.
In the present embodiment, since crown word number is that a line is sequentially arranged, column cutting line can be first chosen, by crown word number area
Area image is that unit is successively cut apart by character.If character information described in the crown word number area image be not it is horizontally arranged,
It is horizontally arranged to character that the crown word number area image is then subjected to rotation process, then carries out above-mentioned cutting operation.
In S302, the crown word number area image is cut into multiple words using the default detent cutting board matched
Accord with subgraph.
In the present embodiment, by identifying the boundary of character, cutting operation is being carried out using default detent cutting board.It lifts
Example property, which is binary image, pixel point value detection is carried out to the subgraph from left to right, when first
The secondary pixel point value for detecting that subgraph column include is 0 pixel, then judges that this is classified as the left margin of a character subgraph；
It is 0 pixel when being consecutively detected a few pixel point values not included that arrange of the subgraph, then judges 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
Then the character boundary of subgraph applies cutting board again and carries out cutting operation.
In invention is implemented, by using identical format and size, character subgraph is intercepted, character subgraph can be convenient for
Storage and identification, to improve the accuracy rate of forge or true or paper money identification.
Further, referring to fig. 4, as another embodiment of the invention, relative to embodiment shown in Fig. 2, this reality
It applies example and identifies that multiple character informations included in multiple character subgraphs of each crown word number area image are done respectively to described
Further refinement, details are as follows:
It is described to identify multiple character informations included in multiple character subgraphs of each crown word number area image respectively
Specifically:
In S401, by row pixel point value every in the multiple character subgraph and each column pixel point value, respectively and in advance
If the corresponding row pixel point value of pixel characteristic value template and column pixel point value in configured list carry out poor square operation, obtain
Multiple difference square values, the corresponding specific character of pixel characteristic value template in the preset configuration list.
In the present embodiment, since character subgraph stores in a digital format, character subgraph is considered as one
A image being made of multiple pixel grid points, the character subgraph each column or row have several pixels, the pixel
Point has pixel point value, for colored image, constitutes the pixel point value by tri- pixel values of RGB；For gray level image, then by
Pixel point value of the gray value of the point as the point；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, template and 10 numeric words comprising corresponding to 26 upper case alphabetic characters
The template of symbol.
Preferably, in the present embodiment, the corresponding preset configuration list of each crown word number area image, 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 carried out with different fonts printing or through typesetting and stretcher strain cause display on have any different,
Therefore be conducive to improve matched accuracy using different lists.
In S402, the multiple poor square value summation is stated to 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 distribution are as follows:The wherein pixel point value distribution of a pixel characteristic value template are as follows: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 the difference square of the two is (510-255)2=65025.Remaining each row
Each Leie time calculates, and the sum of poor square value obtained is the matching numerical value of the pixel characteristic value template.
In S403, in the multiple pixel characteristic value template, the smallest picture of matching numerical value is obtained
Plain characteristic value template, using specific character corresponding to the smallest pixel characteristic value template of matching numerical value as the word
Accord with the corresponding character of subgraph.
In the present embodiment, since the matching value for after poor square operation, obtaining image can effectively indicate multiple
Matching degree between image, therefore, selection matching the smallest corresponding pixel characteristic value template of numerical value, it is believed that the template be with
The character subgraph most similar pixel characteristic value template in preset configuration list.
Preferably, if character pixel template corresponding to matching numerical value minimum is selected using identification strategy there are multiple
Optimum Matching template, the identification strategy specifically: judge whether the identical multiple pixel characteristic value templates of the matching value belong to
In same big class template, if so, using character feature diagnostic method；If it is not, then approaching diagnostic method using center.
In the present embodiment, same big class template refers 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 screen pixel characteristic value template using feature decision method.Illustratively, for word
" 6 " and character " 9 " are accorded with, can detect the area pixel point Distribution value in the character subgraph upper right corner, if only a small amount of in the region
The pixel that point value is 0, then judge the corresponding character of character subgraph for " 6 "；Conversely, then corresponding character is " 9 ", remaining
Each major class character can also be carried out further refinement by the method for same feature decision and be differentiated.
In the present embodiment, center approach diagnostic method refer to reduce borderline region differentiation, that is, leave out first trip first with
And footline terminal column, then carry out poor square matches method.Due to multiple pixel characteristic value templates for being not belonging to same major class
It is identical to match numerical value, it may be possible to cause since the noise on boundary is more；On the other hand, when two characters be not belonging to it is same big
Class, closer to picture centre, difference will be bigger, therefore, can be used and gradually decreases boundary, and the method to compare is judged.
In embodiments of the present invention, the smallest matching template of difference is selected as the character subgraph by poor square matches method
The corresponding templates of picture, to identify the character that character subgraph indicates.This method is realized simply, and simple poor square of fortune is passed through
It calculates, that is, can recognize image character, the time of forge or true or paper money identification is improved, to improve recognition efficiency.
