I read an image: im=cv2.imread('image.jpg')

I divide it into 2 pictures:


I display im1 and im2 separately. It is ok.

But now, I want to save im1 and im2 in combine and display combine which must display me the same image as im. How can I fulfill this ?

@thdrksdfthmn thank you. In fact I have 4 blocks of the same image, all of them with the same size. Can I use push_back in this case too ?

@thdrksdfthmn I tried but the push_back does not exist in Python/numpy

Use np.hstack, np.vstack or np.concatenate, e.g. np.concatenate( [im1,im2], axis=1).
