Displaying results

In fact, we can display the results only if the match method returns a result, right? This can be seen in the following block:

        if match_succsess:
            cv.imshow("res", img_warped)
            cv.imshow("flann", img_flann)
        if cv.waitKey(1) & 0xff == 27:
            break

Displaying images in OpenCV is straightforward and is done by the imshow method, which accepts the name of a window and an image. Additionally, loop termination criteria on the Esc keypress are set. 

Now that we have set up our app, let's take a look at the process flow in the next section.
