Hi, Combination of image deskewing and image inversion should work. Use PSM 11 on processed image, it will detect most of the characters. Thanks, Nikhil On Tue, Nov 1, 2022, 6:16 AM kwmz...@gmail.com wrote: > So I think you could also try using some morphological transformation; I > feel like

So I think you could also try using some morphological transformation; I feel like dilation could help a lot too On Monday, October 31, 2022 at 2:01:36 PM UTC-4 nabil-ak wrote: > https://imagetotext.info/ > > If i use a website like this one it can extract the text perfectly and > they also us

Re: [tesseract-ocr] Help with detecting a code on an image

https://imagetotext.info/ If i use a website like this one it can extract the text perfectly and they also use tesseract. There has to be some preproccesing/setting that makes tesseract detect the text perfectly. nabil-ak schrieb am Montag, 31. Oktober 2022 um 13:55:56 UTC+1: > *I also tried R

*I also tried Rotation but its still not working.* *These are the preprocessing steps that i used:* import cv2 import pytesseract import numpy as np from scipy import ndimage img = cv2.imread('voucher.png') img = cv2.bitwise_not(img) img = cv2.resize(img, None, fx=1.2, fy=1.2, interpolation=cv

Re: [tesseract-ocr] Help with detecting a code on an image

Did you try all the preprocessing steps? Rotation / Deskewing ? I think Tesseract finds it difficult to identify skewed images. On Mon, Oct 31, 2022 at 1:17 PM nabil-ak wrote: > Hello, > > I want to detect a code (combination of characters) on an image in python. > > I already tried EasyOCR
