np array tolist and back

[anthares]

Hi everyone,

I am pretty new to Python and I am seeking some help and guidance.

I use OpenCV to grab frames from video cap:

ret, frame = self.cap.read()

frame.shape here is (480,640,3)

For subsequent processing, I need to serialize the value in order to pass it on to remote consumers:

data = np.fromstring(frame, np.uint8)
message = data.tolist()

On the other end, I am trying to reverse that:

frame = np.array(incoming_message, dtype=np.uint8)
cv2.imwrite('debug.jpg', frame)

but clearly, it is not the right way to do it.
How should I proceed to obtain the original nparray so that I can save it as an image?

Please, advise.

Thanks in advance!
Cheers,
G
