Embodiment 1
In one embodiment, it please refers to: Fig. 1, Fig. 2.
A kind of secret note identification method comprising following steps:
Step S1, determine secret note column and；
Obtain maximum column and and its corresponding position in the secret note；
Step S2, based on the boundary of the column and the determining secret note；
Method that is above-mentioned, determining the boundary of secret note specifically can be such that the position for determining maximum column and place；It is past to be somebody's turn to do
The left side and right progress position of the position at maximum column and place are mobile, if the stain number of the column is less than certain predetermined value or company
The stain number of continuous one section of column is respectively less than certain preset value, it is determined that the column or the region are boundaries.
Step S3, based on the boundary and the maximum column and in secret note, the secret note is divided into left part by corresponding position
Point and right half；
It is above-mentioned, specifically the left-hand component for referring to maximum column and corresponding position to secret note is left half；Maximum column and right
The part on the position answered to the right of secret note is divided into right half.
Step S4, it obtains described in being greater than in the first row and the right half that are greater than first threshold in the left half
The secondary series of first threshold；
Step S5, the column to the first row and with the column of the secondary series and sum, obtain the sum value；
Step S6, determination and value and the maximum column and difference formed less than each first row of the first preset value
Set；
It is above-mentioned, it should be noted that when first row column and with the column of secondary series and and value and maximum column
When the difference of sum is less than the first preset value, then obtain the first row, and by the column of the secondary series and be changed to 0, to avoid this
The former of two column arranges and is repeated calculating.
Can be as an example: if the column of a first row of left half and be X, the column of a secondary series of right half and be Y,
When the following conditions are met:
Condition one, X and Y are all larger than first threshold, such as 40；
Condition two, X and Y's and value and maximum column and numerical value it is close, for example be no more than the first preset value 20.
It is put into set at this point, obtaining the first row, and by the column of the secondary series and is changed to 0.
Continue to obtain another first row, when the first row and a secondary series meet above-mentioned two condition again, and will
The first row is put into set, and by the column of the secondary series and is changed to 0.It is understood that when the first row and this
Two column replace another secondary series when being unsatisfactory for above-mentioned two condition, when the first row and all secondary series be all unsatisfactory for it is above-mentioned
When two conditions, the first row is abandoned.Until all first rows complete the operation of above-mentioned condition, and by all the got
One column are put into a set.
Step S7, the first row in a set is successively chosen, determines first row in the set and selected
Column sum difference less than the second preset value first row quantity；
It is above-mentioned, it should be noted that a first row being selected in the set makees quilt in the set of difference with it
Another first row chosen can be the same first row.
Second preset value can be 20, in another embodiment, or 10 or 15.
Specifically, it can illustrate are as follows: first first row being selected in the set and be selected in the set second
A first row makees difference, when the difference is less than 20, then count number one.Unceasingly, first first row is successively and except second
It is poor that other first rows (including itself) outside a first row are made, and when the difference is less than 20 each time, then accelerates primary.When
After the completion of first first row and other all first rows make difference, choose another first row in addition to first first row with
It is poor that other first rows (including itself) in addition to first first row are made, and when the difference is less than 20 each time, then increases number
Amount is primary.Finally, after (including itself) finishs difference to each first row between each other, final quantity is denoted as the quantity
Maximum value.
Step S8, the maximum value in the quantity is determined；
Step S9, judge whether the maximum value is greater than third preset value；
Above-mentioned, it can also be 2,3 etc. that in the present embodiment, third preset value, which can be 1,.
Step S10, if the determination result is YES, it is determined that the secret note has fracture；
If step S11, judging result is no, it is determined that the secret note is normal.
Therefore, a kind of secret note identification method of the present embodiment, can more accurately judge the fracture of secret note, can also incite somebody to action
The case where secret note tilts excludes the situation of secret note fracture, improves the accuracy of paper money discrimination.
In the present embodiment, the column of secret note " determine and " specifically:
Determine column included by the secret note；
Determine that each column include the number of point；
Above-mentioned, secret note refers to the black lines that safety line is formed under infrared transmitting；The point, forms the black lines
Stain.
By be less than second threshold number be set as column and.
It is above-mentioned, refer to by be less than second threshold stain number be set as the column column and.
In the present embodiment, the left part is divided into maximum column and corresponding position to the secret note within the scope of the secret note
Left margin range；
The right part is divided into the model of maximum column and right margin of the corresponding position to the secret note in the secret note region
It encloses.
In the present embodiment, further includes:
Step S101, it to the column and backs up.(please referring to Fig. 2)
It is above-mentioned, refer to the column to column each in secret note and backs up.
In the present embodiment, the first threshold is set after carrying out binaryzation to the secret note.
Embodiment 2
In another embodiment, it please refers to: Fig. 3.
A kind of secret note identification apparatus comprising:
First determining module 1: for determine secret note column and；
Second determining module 2: for the boundary based on the column and the determining secret note；
Division module 3: for the secret note to be divided into left half and right half based on the boundary；
Obtain module 4: big greater than in the first row and the right half of first threshold in the left half for obtaining
In the secondary series of the first threshold；
Summation module 5: for the first row column and with the column of the secondary series and sum, obtain the sum value；
Third determining module 6: for determine and be worth with maximum column and each described first of difference less than the first preset value
Column are formed by set；
4th determining module 7: for successively choosing the first row in a set, determine in the set with it is selected
Quantity of the difference of the column sum of the first row taken less than the first row of the second preset value；
5th determining module 8: for determining the maximum value in the quantity；
Judgment module 9: for judging whether the maximum value is greater than third preset value；
It identifies module 10: being broken for when the judgment result is yes, determining that the secret note exists, and, work as judging result
When being no, determine that the secret note is normal.
Further, in the present invention, the column of secret note " determine and " specifically:
Determine column included by the secret note；
Determine that each column include the number of point；
By be less than second threshold number be set as column and.
Further, in the present invention, the left part is divided into maximum within the scope of the secret note arrange with corresponding position extremely
The range of the left margin of the secret note；
The right margin is the model of maximum column and right margin of the corresponding position to the secret note in the secret note region
It encloses.
Further, in the present invention, further includes:
Backup module 11: for arranging and backing up to described.
Further, in the present invention, the first threshold is set after carrying out binaryzation to the secret note.
It will be appreciated by those skilled in the art that the module in device in implement scene can be described according to implement scene into
