问题 I am getting the following error when trying to print a simple test image to text. I've verified that I have Pillow (PIL 1.1.7) and tried uninstalling and reinstalling pytesseract. The file paths are correct because if I change them I get another error saying that the file cannot be found. My code: from PIL import Image import pytesseract pytesseract.pytesseract.tesseract_cmd= r'C:\Users\bbrown2\AppData\Local\ Programs\Python\Python37\Scripts\pytesseract' img = r'C:\Users\bbrown2\Desktop\test

问题 I'm trying to get PyTesseract OCR to read digits from this simple and well cropped Image, but for some reason it's just not able to do this. from PIL import Image import pytesseract as p def obtain_balance(a): im = Image.open(a) width,height = im.size a = 300*5 - 120 # print(width,height) left = 155+a top = 5 right = 360+a bottom = 120 m1 = im.crop((left, top, right, bottom)) text = p.image_to_string(m1,lang='eng',config='--psm 13 --oem 3 -c tessedit_char_whitelist=0123456789').split() print

问题 I am trying to use pytesseract in Python but I always end up with the following error: raise TesseractNotFoundError() pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path However, pytesseract and Tesseract are installed on my system. Example code that produces this error: import cv2 import pytesseract img = cv2.imread('1d.png') print(pytesseract.image_to_string(img)) How do I resolve this TesseractNotFoundError? 回答1: I tried adding to the path

问题 I am trying to deploy an app on the Google App Engine that also has OCR function. I downloaded the tesseract using homebrew und using pytesseract to wrap in Python. The OCR function works on my local system, but it does not when I upload the app to the Google App Engine. I copied tesseract folder from usr/local/cellar/tesseract and pasted into the working directory of my app. I uploaded the tesseract files and also pytesseract files to appengine. I have specified the path for tesseract with

问题 Above is the image ,I have tried everything I could get from SO or google ,nothing seems to work. I can not get the exact value in image , I should get 2.10 , Instead it always get 210. And it is not limited to this image only any image which have a decimal before number 1 tesseract ignores the decimal value. def returnAllowedAmount(self,imgpath): th = 127 max_val = 255 img = cv2.imread(imgpath,0) #Load Image in Memory img = cv2.resize(img, None, fx=2.5, fy=2.5, interpolation=cv2.INTER_CUBIC)

问题 Recently, I took a project. Converting a scanned PDF to searchable PDF/word using Python tesseract. After few attempts, I could able to convert scanned PDF to PNG image files and afterwards, I'm struck could anyone please help me to convert the PNG files to Word/PDF searchable.my piece of code attached Please find the attached image for reference. Import os Import sys from PIL import image Import pytesseract from pytesseract import image_to_string Libpath =r'_______' #site-package Pop_path=r'

问题 I have been working on PyTesseract OCR and converting PDF to JPEG inorder to OCR the image. A part of the image has a black background and white text, which Tesseract is unable to identify, whereas all other parts of my image are being read perfectly well. Is there a way to change a part of the image that has black background? I tried a few SO resources, but doesn't seem to help. I am using Python 3, Open CV version 4 and PyTesseract 回答1: opencv has a bitwise not function wich correctly
