Hi all,
I'm learning tesseract in python and I'm trying to detect all the text
regions using pytesseract.image_to_data() and then extract the text from
each region one by one. My code below attempts to do this:
import cv2
import pytesseract
from pytesseract import Output
pytesseract.pytesseract.tesseract_cmd = r'C:\Program
Files\Tesseract-OCR\tesseract.exe'
img = cv2.imread('cocacola_19.png')
d = pytesseract.image_to_data(img, output_type=Output.DICT)
n_boxes = len(d['text'])
img_rect = img.copy()
c=0
for i in range(n_boxes):
if int(d['conf'][i]) > 50:
(x1, y1, w1, h1) = (d['left'][i], d['top'][i], d['width'][i], d[
'height'][i])
img_rect = cv2.rectangle(img_rect, (x1, y1), (x1 + w1, y1 + h1), (0,
255, 0), 2)
# cv2.imwrite('rect.jpg', img[y1:y1+h1, x1:x1+w1])
out = pytesseract.image_to_string(img[y1:y1+h1, x1:x1+w1])
if(len(out)==0):
out = pytesseract.image_to_string(img[y1:y1+h1, x1:x1+w1],
config='--psm 3')
c+=1
However, it does not work. For example, the first region of text contains
'THE'. But pytesseract.image_to_string() returns an empty string. Why does
this happen? My input image is attached.
Thanks in advance
