问题 I want to extract the text from an image in python . In order to do that, I have chosen pytesseract . When I tried extracting the text from the image, the results weren't satisfactory. I also went through this and implemented all the techniques listed down. Yet, it doesn't seem to perform well. Image: Code: import pytesseract import cv2 import numpy as np img = cv2.imread('D:\\wordsimg.png') img = cv2.resize(img, None, fx=1.2, fy=1.2, interpolation=cv2.INTER_CUBIC) img = cv2.cvtColor(img, cv2

How to use tesseract.js on a base64 encoded image

由 孤街醉人 提交于 2021-02-10 09:37:37
问题 I'm working on a personal project where I'm given a base64 string that is some image. I'm trying to run tesseract OCR on that image, however, I'm not sure how to do that. var base64String = 'data:image/jpg;base64,' + givenImage; var buffer = Buffer.from(base64String, 'base64'); var output = tesseract.recognize(buffer); return output; This doesn't seem to work at all and I'm not really sure why. This is run on a node.js server. 回答1: I think you're very nearly there. When parsing the base64

How to improve OCR with Pytesseract text recognition?

问题 Hi I am looking to improve my performance with pytesseract at digit recognition. I take my raw image and split it into parts that look like this: The size can vary. To this I apply some pre-processing methods like so image = cv2.imread(im, cv2.IMREAD_GRAYSCALE) image = cv2.GaussianBlur(image, (1, 1), 0) kernel = np.ones((5, 5), np.uint8) result_img = cv2.blur(img, (2, 2), 0) result_img = cv2.dilate(result_img, kernel, iterations=1) result_img = cv2.erode(result_img, kernel, iterations=1) and
