Hi all, I just run chapter 3 markerless AR sample. The cube is flying/flashing everywhere.

am I doing something wrong?

Hi. It's hard to pinpoint the cause, but most likely it's due to poor keypoint matching. It could be caused by template you've choosen, video quality and resolution or even the OpenCV version.
