OCR In Linux using python

Hello programmers, today we are going to perform OCR operation on image using python on Linux operating system. Before start coding let’s get to know

What is OCR ?

Optical character recognition or optical character reader (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example from a television broadcast).

So I hope you got basic idea about what is OCR and how it can be applied. So we are ready to perform OCR operation. To do this we have to complete following conditions.

Linux operating system (Latest one)

Python 3.x installed

After satisfying above requirements we need few libraries like Pillow, Pytesseract. To install this libraries just open terminal and enter following commands

pip3 install Pillow

pip3 install pytesseract

After installing libraries we have done almost operation. now for coding open terminal and type following code

Code:

from PIL import Image 
import pytesseract 
print (pytesseract.image_to_string(Image.open('test.png')))

That’s it. here in this line

print (pytesseract.image_to_string(Image.open('test.png')))

test.png is an sample image we used to do OCR operation. we also used another image as test2.png as sample image and results are

test

Test.png

test2

Test2.png

And here are OCR results of above images are

ocr_result

Test2.png OCR result:

ocr_test_2_result

So here it ends. You have completed performed OCR operation. You can use any other image instead of test image. Sooner we will try to bring this program in windows also. Till then try it with your own and any problem persist feel free to comment below and also help us grow big by sharing this with your programmer friend circle.

Thank you.. Happy Coding..
