Save images obtained from OpenCV on another computer (using FTP or other way)

Question

I am taking pictures using the OpenCV from my webcam, and after I have identified the face, I save the face image using a cv2.imwrite in a folder in my computer.

Now, my question is how can I save the images in path on another computer?

I mean, for example, using FTP, I can directly add another path to storing the images to cv2.imwrite and put them in the another computer?

Answer 1

You need to use cv2.imencode to store the image to memory:

retval, buffer = cv2.imencode('.jpg', image)

Then upload the buffer:

from ftplib import FTP
from io import BytesIO

ftp = FTP('ftp.example.com')
ftp.login('username', 'password')

flo = BytesIO(buffer)
ftp.storbinary('STOR test.jpg', flo)
