I have a task to track a car in a video. And I decide to use the ORB feature and Flann. Firstly select the car in the frame. Secondly match the selected car and the next frames. But when the area of selected ROI is small, an error occor and the program crashes. So I choose the BFMatcher instead of Flann. However, the same problem occor. I guess there is something wrong in the parameters of Flann. But I have no idea how to adjust the parameters. (the Flann and the BFMatcher have some bugs?) Could you help me?
