Hi
I posted this on stackoverflow but got no response...
I am trying to read subtitles from an image taken from the news using
tesserract on python.
for some reasons I get better results when saving the file using plt and
using tesseract reading it from there
1. Why is that?
2. How can I refine my results using cv2?
import urllib3import requestsimport numpy as npimport pytesseractimport
matplotlib.pyplot as pltfrom PIL import Imagedef downloadFile():
url =
'https://drive.google.com/uc?export=download&id=0B7t_yZLolnbiaVpicnEwbDRjTmc'
http = urllib3.PoolManager()
r = http.request('GET',url)
f = open('testing.npy', 'wb')
f.write(r.data)
downloadFile()
frame = np.load('testing.npy')
new_frame = frame[170:210,8:195]
plt.imshow(new_frame)
plt.axis('off')
plt.savefig('plt.png')print('from array: ' +
pytesseract.image_to_string(Image.fromarray(new_frame),lang = 'eng'))print(
'from plt: ' + pytesseract.image_to_string(Image.open('plt.png'),lang = 'eng'))
Thank you!
