Embodiment 1
In one embodiment, refer to：Fig. 1, Fig. 2.
A kind of secret note authentication method, it comprises the following steps：
Step S1, the row for determining secret note and；
Obtain maximum column and and its corresponding position in the secret note；
Step S2, based on the row and determine the border of the secret note；
Method that is above-mentioned, determining the border of secret note, specifically can be as follows：It is determined that maximum row and the position at place；It is past to be somebody's turn to do
Maximum row and the left side and the right carry out position movement of the position at place, if the stain number of the row is less than certain predetermined value or company
The stain number of continuous one section of row is respectively less than certain preset value, it is determined that the row or the region are borders.
Step S3, based on the border and the maximum column and in secret note, the secret note is divided into left part by corresponding position
Divide and right half；
It is above-mentioned, specifically it is left half to refer to maximum column and corresponding position to the left-hand component of secret note；Maximum column and right
The part on the position answered to the right of secret note is divided into right half.
It is more than the first row of first threshold in step S4, the acquisition left half, and is more than in the right half described
The secondary series of first threshold；
Step S5, the row to the first row and the row with the secondary series and sum, obtain and be worth；
Step S6, determine 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 is necessary to explanation, when the row of first row and the row with secondary series and and be worth and maximum column
When the difference of sum is less than the first preset value, then obtain the first row, and by the row of the secondary series and be changed to 0, with avoid this
The former of two row arranges and computed repeatedly.
Can be as an example：If row of a first row of left half and for X, row of a secondary series of right half and be Y,
When meeting following condition：
Condition one, X and Y are all higher than first threshold, such as 40；
Condition two, X and Y's and value with maximum column and numerical value approach, such as no more than the first preset value 20.
Now, obtain the first row to be put into set, and by the row of the secondary series and be changed to 0.
Continue to obtain another first row, when the first row and a secondary series meet above-mentioned two condition again, general again
The first row is put into set, and by the row of the secondary series and is changed to 0.It is understood that when the first row with this
Two row change 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
During two conditions, the first row is abandoned.Until all first rows complete the computing of above-mentioned condition, and by it is all get the
One row are put into a set.
Step S7, the first row chosen successively in a set, determine first row in the set and selected
Row sum difference be less than the second preset value first row quantity；
It is above-mentioned, it is necessary to explanation, a first row being selected in the set, quilt in the set with doing difference with it
Another first row chosen can be same first row.
Second preset value can be 20, in another embodiment, or 10 or 15.
Specifically, it can be exemplified as：First first row being selected in the set and be selected in the set second
Individual first row makees difference, when the difference is less than 20, then count number one.Unceasingly, first first row successively with except second
Other first rows (including itself) outside individual first row make poor, when the difference is less than 20 each time, then accelerate once.When
First first row is made with other all first rows after the completion of difference, choose another first row in addition to first first row with
Other first rows (including itself) in addition to first first row make poor, when the difference is less than 20 each time, then increase number
Amount is once.Finally, after (including itself) finishs difference to each first row each other, final quantity is designated as the quantity
Maximum.
Step S8, the maximum determined in the quantity；
Step S9, judge the maximum whether be more than the 3rd preset value；
Above-mentioned, in the present embodiment, the 3rd preset value can be 1, can also be 2,3 etc..
Step S10, if the determination result is YES, it is determined that the secret note has fracture；
If step S11, judged result are no, it is determined that the secret note is normal.
Therefore, a kind of secret note authentication method of the present embodiment, can more accurately judge the fracture of secret note, can also be by
The inclined situation of secret note excludes the situation of secret note fracture, improves the accuracy of paper money discrimination.
In the present embodiment, the row of secret note " determine and " is specially：
Determine the row included by the secret note；
Determine that each row include number a little；
Above-mentioned, secret note refers to the black lines that safety line is formed under infrared transmitting；The point, constitutes the black lines
Stain.
By the number less than Second Threshold be set to row and.
It is above-mentioned, refer to by the number less than the stain of Second Threshold be set to the row row and.
In the present embodiment, the left part is divided into row maximum in the range of the secret note and corresponding position to the secret note
Left margin scope；
The right part is divided into the model of row and right margin of the corresponding position to the secret note maximum in the secret note region
Enclose.
In the present embodiment, in addition to：
Step S101, to it is described row and back up.(referring to Fig. 2)
It is above-mentioned, refer to the row of each row in secret note and back up.
In the present embodiment, the first threshold is the secret note to be carried out set by after binaryzation.
Embodiment 2
In another embodiment, refer to：Fig. 3.
A kind of secret note identification apparatus, it includes：
First determining module 1：For determine secret note row and；
Second determining module 2：For based on the border for arranging and determining the secret note；
Division module 3：For the secret note to be divided into left half and right half based on the border；
Acquisition module 4：It is more than the first row of first threshold in the left half for obtaining, and in the right half greatly
In the secondary series of the first threshold；
Summation module 5：For the row to the first row and the row with the secondary series and sum, obtain and be worth；
3rd determining module 6：For determine and be worth with maximum column and difference be less than the first preset value each described first
The formed set of row；
4th determining module 7：For choosing the first row in a set successively, determine in the set with it is selected
The difference of the row sum of the first row taken is less than the quantity of the first row of the second preset value；
