Hello, I'm newbie in CV programming. Based on tutorial in Features2D I found that the detection of two images is not difficult. But the results of these tutorials is to show the keypoints of the two images and draw a line. My question is can I just get a boolean if the two images are the same or not. I do not need to display images from two matches Mat, I just need to know that both Mat is the same or not.

Thanks in advance for the reply.

Let's say I have a picture of "A", then I insert the picture "A" is to the database. I also have a printed picture "A" on a piece of paper. When I show a printed picture of "A" to the camera, then my program will be able to instantly recognize the picture "A" is.

Thanks in advance for the reply.
