Accesing Memory Address

edit

Well I will explain my problem I am using a wrapper from a c++ to a python program that retrieve a frame from a camera an store it on a Mat*, but when I try to obtain the image in the python script what I am obtaining is a memory address and no the information of the image itself.

Anyone know how can I solve it?

I show my main scrip and the terminal's output

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import cv2
import time
import ctypes
from biblioteca import lib

objectInstance = lib.classInstance();

initializace = lib.initializeCamera(objectInstance);

print initializace

frame = lib.getFrame(objectInstance)
frame = lib.getFrame(objectInstance)
print frame
time.sleep(5)
lib.freeClass(objectInstance)

Output:
