1031) gray proces: before carrying out gray processing processing, need to verify the color category of the unstructured nuclear power file
Property, if verification passes through, it may be considered that the color of each pixel may be expressed as: C=xR+yG+zB in file, wherein x+y+z
=1.Then each pixel in color document can be weighted gray processing processing: Gray=(ω according to following formulaRR+ωGG+ωBB)÷3.Since human eye is most sensitive to green, red is taken second place, minimum to the sensibility of blue, therefore makes ωG> ωR
> ωBIt will obtain gray level image more easy to identify.Distinguishingly, setting weight is as follows, ωR=0.299, ωB=0.587, ωG=
0.114, ωG=0.114；ωR=0.299；ωB=0.587, the obtained gray level image effect is best.
1032) binary conversion treatment: since pretreated effect quality directly affects the performance of subsequent Text region, and nuclear power
The file content identified in file is mostly letter or number, and therefore, it is necessary to carry out binary conversion treatment to picture, processing formula is such as

1, and be odd number, generally 3*3) filter, and be odd number, generally 3*3), find intermediate value in all boundary values, as
The numerical value of the central point.For example, 9 pixels of the 3*3 chosen for filter, if this 9 pixels before filtering
Value is respectively as follows:
0 0 0
0 255 0
0 0 0
Obviously, intermediate point is noise, and after the filtering noise reduction process of this step, it is each that the 255 of intermediate point become periphery
The intermediate value (average) 0 of point, i.e., after noise reduction, become
0 0 0
0 0 0
0 0 0

Image edge on straightway；
1052) to identifying that the picture at edge carries out slant correction: straightway obtained in the previous step is successively decreased row by length
Sequence selects several longest straightways to calculate several straightways tilt angle relative to horizontal direction, takes this several
Tilt angle of the intermediate value of the tilt angle of a straightway as whole image, the tilt angle based on whole image can pass through
Rotation image carries out slant correction to it；
1053) picture after being partitioned into slant correction: the straightway on retention level direction and vertical direction removes other
Straightway；Calculate the distance between the different straightway endpoints that remain, if it is less than the threshold value of setting, then to straightway into
Row connection, can so obtain the unit table images of table；
1054) single block of information picture is extracted in positioning: firstly, obtaining position letter according to the file template in verification rule
Breath, according to the position of location information location information block picture；Secondly, being known after the position of location information block picture by edge
Other algorithm takes off block of information picture；Finally, the block of information picture for taking off out is temporarily saved according to rule.Wherein, position
Confidence breath includes the page number, starting point and end point.In one specific embodiment, the information that edge algorithms will be taken off can use
Block picture saves as BMP format.
