问题 I am using pytesseract to extract text from images. Before extracting text with pytesseract, I use Pillow and cv2 to reduce noise and enhance the image: import numpy as np import pytesseract from PIL import Image, ImageFilter, ImageEnhance import cv2 img = cv2.imread('ss.png') img = cv2.resize(img, (0,0), fx=3, fy=3) cv2.imwrite("new.png", img) img1 = cv2.imread("new.png", 0) #Apply dilation and erosion kernel = np.ones((2, 2), np.uint8) img1 = cv2.dilate(img1, kernel, iterations=1) img1 =

问题 I am trying to extract data from a scanned form. The form has a standard format similar to the one shown in the image below: I have tried using pytesseract (tesseract OCR) to detect the image's text and it has done a decent job at finding the text and converting the image to text.
