How to extract the text displayed in a dot matrix LED display
I am using the example code given by pytesseract to test. But I am failing.
try: from PIL import Image except ImportError: import Image import pytesseract # If you don't have tesseract executable in your PATH, include the following: pytesseract.pytesseract.tesseract_cmd = r'<full_path_to_your_tesseract_executable>' # Example tesseract_cmd = r'C:\Program Files (x86)\Tesseract-OCR\tesseract' # Simple image to string print(pytesseract.image_to_string(Image.open('test.png')))
From the sample image I need the output as the number and alphabets given.
If my image have only one number totally filled in whole display that number alone should be in result.. Am I using the right tools? or should I look into opencv and machine learning to extract characters from display.
