Testing Pytesseract on Clean Example Files

The Pytesseract that we are testing below is the one downloaded using homebrew/sudo apt-get install and not the one from pip. The results will be printed to the terminal.

Example 1

$ tesseract tesseract_inputs/example_01.png stdout

This should output Testing Tesseract OCR

Example 2

$ tesseract tesseract_inputs/example_02.png stdout

This should output PyImageSearch

Example 3

$ tesseract tesseract_inputs/example_03.png stdout

This should output 650 3428

Testing Pytesseract on Noisy Example Files

The results will be printed to the terminal.

	Tesseract	ocr.py file
Run	$ tesseract images/example_01.png stdout	$ python3 ocr.py --image images/example_01.png
Result	Noisyimage to test Tesseract OCR	Noisy image to test Tesseract OCR

	Tesseract	ocr.py file
Run	$ tesseract images/example_02.png stdout	$ python3 ocr.py --image images/example_02.png --preprocess blur
Result	_ Tesseract Will Fail With Noisy _ Backgrounds —	Tesseract Will Fail With Noisy Backgrounds

	Tesseract	ocr.py file
Run	$ tesseract images/example_03.png stdout	$ python3 ocr.py --image images/example_03.png
Result	In order to make the most of this, you will need to have alittle bit of programming experience. All examples in this book are in the Python programming language. Familiarity with Python or other scripting languages is suggested, but not required. You'll also need to know some basic mathematics. This book is hands-on and example driven: lots of examples and lots of code, so even if your math skills are not up to par, do not worry! The examples are very detailed and heavily documented to help you follow along.	In order to make the most of this, you will need to have alittle bit of programming experience.
