This code works fine if the ara. set the value to 6. I tried to not grayscale the image, but that didn't work either. I'm using pytesseract to try extract text numbers from image. We then pass an image file to the ocr () function to extract text from the image. Original image I have captchas like with circles in the background and i need to extract the words. To resolve the issue, we can use --psm 8, telling Tesseract to bypass any page segmentation methods and instead just treat this image as a single word: $ tesseract designer. tesseract_cmd = r'C:Program FilesTesseract-OCR esseract'. First: make certain you've installed the Tesseract program (not just the python package) Jupyter Notebook of Solution: Only the image passed through remove_noise_and_smooth is successfully translated with OCR.
