We’ll use OpenCV to build the actual image processing component of the system, including: To learn how to automatically In this tutorial, you will learn how to extract text and numbers from a scanned image and convert a PDF document to a PNG image using Python libraries such as wand, pytesseract, cv2, and PIL. py --image The document scanner follows these key steps: Edge Detection: Using Canny edge detection to identify document boundaries. Gain access to Jupyter Notebooks for this tutorial and other PyImageSearch guides Enhance the document scanner to extract text and numbers. Thresholding, Finding The scanner takes a poorly scanned image, finds the corners of the document, applies the perspective transformation to get a top-down view of the document, sharpens the image, and applies an adaptive color threshold to clean up the Optical Character Recognition (OCR): Image alignment (often called document alignment in the context of OCR) can be used to build automatic form, invoice, or receipt scanners.
