Detect punctuation marks on ocr

Hi,

I'm trying to do an application regarding ocr.

How can the ocr detect punctuation marks like period?

i trained an image in the "ocr trainer" the ocr trainer detected the numbers and period, but "period" is not recognized when i tried to write the output to .txt file

here is the sample processed image

i already processed the original image using the following code snippet

str = "testimage.jpg";

I = imread('testRawImage.jpg');

I = rgb2gray(I);

Icorrected = imtophat(I,strel('cube',8));

contrastAdjusted = imadjust(Icorrected);

BW1 = imbinarize(contrastAdjusted);

imwrite(BW1,str)

output in txt file is (period is not recognized, but i checked on ocr trainer the period is recognized using the ocr trainer):

1420545

1420575

142024

142031

i used fprintf to write in txt file.

if it helps i used the language i made using the ocr trainer.

this is my ocr snippet

ocrResults = ocr(H, 'Language','test.traineddata');

What are H and 'test.traineddata'? Please attach the script so we can try it ourselves. And attach the original image rather than the processed image.

hi i uploaded the files i used for the application, unfortunately I cannot upload the .txt file and traineddate file because of the file format.

test.traineddata is the output of ocr trainer

i got it working i just changed the ocr to

ocrResults = ocr(H,'CharacterSet','.0123456789');

Thanks
