Description
Technical field
The present invention relates to judicial expertise technical fields, specifically, more particularly to a kind of judging Zhu based on YIQ color mode
The method of black timing.
Background technique
Red and black timing refers to that printed text and writing, printing, duplicating word are formed by sequencing, and " Zhu " here is finger mark
Text is formed by ink paste, stamp-pad ink, and " ink " refers to all writing strokes overlapped with printed text, by writing material, print copying material
Material is formed.
Currently, judging that the method for red and black timing is all based on greatly the external appearance characteristic and physicochemical property of sample.Wherein based on outer
Seeing feature and carrying out the process of red and black timing judgement is mainly according to the tables such as the variation of " red and black " intersection pigment color, hierarchical structure
Feature is seen to be judged；The process for carrying out the judgement of red and black timing based on physicochemical property is primarily referred to as the dissolution according to red and black colorant
The physical and chemical indexes such as property, optical characteristics, chemical component, adsorption capacity are judged.Currently, widely used judgment method includes light
Learn (electronics) microscopic method, three-dimensional spectroscopic methodology, electron probe and spectroscopy, microscopic spectrophotometry, infrared microscopy optical imagery
Technology, Fluorescent examination method, stripping method, decoloring method etc..
But existing external appearance characteristic and physicochemical property based on sample carries out in the method for red and black timing judgement, although
It is mainly carried out by all kinds of accurate experimental facilities in detection process, but the meeting pair in observation and analytic process of the subjective factor of people
Judgement conclusion generates large effect.
Different from above two method, the present invention is based on digitalized signatures, by digitized process, by color by sense organ table
As switching to data characteristics, in conjunction with big data processing method, judgement conclusion is directly obtained.Minimum level reduces human factor to conclusion
Influence.
Summary of the invention
The technical issues of being affected according to existing red and black time-series rules method set forth above by subjective factor, and provide
A method of red and black timing is judged based on YIQ color mode.The present invention is mainly utilized the sense of the colouring information in red and black region
Official's presentation is converted into digitalized signature by YIQ color mode data, carries out data analysis using data mining technology, directly
Red and black timing judgement conclusion is obtained, to utmostly reduce influence of the human factor in the judgement of red and black timing.
The technological means that the present invention uses is as follows:
The method that red and black timing is judged based on YIQ color mode, is included the following steps:
Step 1: preparation master sample identical with the writing type of sample red and black overlapping region to be detected, wherein writing
Type includes handwriting and printing writing, master sample include printed text in upper and printed text at lower two kinds；
Step 2: the red and black overlapping region of scanning standard sample and sample to be detected, scanning result are stored as JPEG lattice respectively
Formula picture file；
Step 3: corresponding to two kinds of master samples and sample to be detected respectively using 3*3 pixel or 5*5 pixel as acquisition unit
Picture file carry out pixel sampling, obtain picture file in red and black overlapping region 100-200 group YIQ color mode number
According to；
Step 4: using SPSS software to the YIQ color mode number of the red and black overlapping region of master sample and sample to be detected
According to progress Mann-Whitney inspection；
According to the asymptotic conspicuousness P value inspection result of bilateral, when some in sample to be detected and two kinds of master samples Y,
I, when the asymptotic conspicuousness P value of Q data is greater than 0.05, the otherness of sample and master sample to be detected is not statistically significant；
According to the asymptotic conspicuousness P value inspection result of bilateral, when some in sample to be detected and two kinds of master samples Y,
I, when the asymptotic conspicuousness P value of Q data is less than 0.05, it is same total to show that the data for detecting sample and master sample are not from
Body, then the red and black timing of sample to be detected and the red and black timing of the master sample are opposite.
Further, in step 1, the image size of picture file storage is 600dpi-1200dpi, image type 24
Position is full-color.
Further, handwriting, printing writing and the printed text generated when preparing master sample respectively with sample to be detected
Pen, the printing device used is identical with stamp-pad ink/ink paste.
Further, in step 3, according to such as after the RGB color mode data of red and black overlapping region in acquisition picture file
RGB color mode data is converted to YIQ color mode data by lower formula:
Y=0.299R+0.587G+0.114B
I=0.596R-0.275G-0.321B
Q=0.212R-0.523G+0.311B.
Compared with the prior art, the invention has the following advantages that
1, the method provided by the invention that red and black timing is judged based on YIQ color mode, by with red and black overlapping region
The foundation that YIQ color mode data judge as red and black timing realizes influence of the subjective factor for reducing people to judgement conclusion.
2, the method provided by the invention that red and black timing is judged based on YIQ color mode, by using Principle of Statistics into
Row data processing guarantees the accuracy of judging result.
3, the method provided by the invention that red and black timing is judged based on YIQ color mode, it is easy to operate, do not need appearance inspection
The expensive device surveyed and used in Physico-chemical tests.
To sum up, it applies the technical scheme of the present invention the sense organ presentation of the colouring information in red and black region, passes through YIQ color mould
Formula data are converted into digitalized signature, and carry out data processing, directly obtain red and black timing judgement conclusion, utmostly reduce people
For influence of the factor in the judgement of red and black timing.Therefore, technical solution of the present invention solves existing red and black time-series rules side
The problem of method is affected by subjective factor.
Based on the above reasons the present invention can judicial expertise and and the fields such as the inspection of document be widely popularized.
