To perform OCR on an image, its important to preprocess the image. The idea is to obtain a processed image where the text to extract is in black with the background in white. Here's a simple approach using OpenCV and Pytesseract OCR. To do this, we convert to grayscale, apply a slig...
Once you install the packages, you are now ready to write your Python code to extract text from images. Go to the folder where the image files you want to extract text are stored. Create a text file and change its name toextract.py. You can change the text file to any name, but ma...
