Using Tesseract OCR with Python — Install & Code

AI & Agents intermediate 5 min read $0.01 Updated 2026-07-31

Using the Tesseract OCR engine from Python: installing pytesseract/OpenCV and Tesseract itself, extracting text from an image file (grayscale + image_to_string), a live webcam OCR loop with thresholding, and the preprocessing (thresholding, denoising, deskewing) that improves real-world accuracy.

Tesseract turns images into text, and with OpenCV + Python you can build document scanners and live-camera readers. This guide covers installing the pieces, reading text from an image file, and running real-time OCR on a webcam feed — plus the preprocessing that boosts accuracy.
