There is text to account for one-row pixels, if next line still finds black picture element, that just adds the text of current record here
One-row pixels height, until certain a line is entirely white pixel, such a line text finishes, even if there is black picture element again below
It is the second row text.
Each row text record end all compares with lastrow text, and the feature choosing height according to addressee's cell-phone number is higher
A line text leave, others are skipped, until traversal terminate thus just obtain understand analysis object lower edges, also just cut
Addressee's cell-phone number region has been taken out, can be sent directly to download to the offline Tesseract OCR identification in terminal,
Tesseract OCR software can carry out judging whether it is cell-phone number to the text identified first (can be according to the digit of cell-phone number
For 11 and number feature, after being determined as digital text first, then judge whether it is cell-phone number), in identifying picture
Content be cell-phone number after, then using Tesseract OCR carry: recognizedBlockByIteratorLevel:G8P
IteratorLevelSymbol recognition methods obtains the accuracy and coordinate of each number in cell-phone number；
The coordinate of each number is integrated, the precise region of whole mobile phone number is obtained；
If the accuracy of the bits per inch word of cell-phone number is both greater than 70, it is considered as cell-phone number identification correctly, returns to correct hand
Machine number；
Hand is intercepted by the precise region obtained again if the accuracy of the bits per inch word of cell-phone number is not both greater than 70
The picture of machine precise region, and upload to the identification of OCR server；
If two recognition results that Tesseract OCR server returns are identical, or in two recognition results returned extremely
Rare one with Tesseract OCR identification facility identical then assert cell-phone number identify successfully provided to express delivery person it is corresponding

convertScaleAbs(cimageX16s,imageSobelX,1,0)；
convertScaleAbs(cimageY16s,imageSobelY,1,0)；
Out=imageSobelX-imageSobelY；
if(show)
Imshow (" Sobelx-y difference figure ", out)；
return out；
}
Mean filter processing is for eliminating high-frequency noise:
Mat MyClass::getBlur(Mat image,bool show)
{
Mat cimage；
blur(image,cimage,Size(3,3))；
if(show)
Imshow (" mean filter figure ", cimage)；
return cimage；
}
Binary conversion treatment reduces the data volume in image, highlights the profile of bar code:
Corrosion expansion is for eliminating noise spot, merging bar code region:
