Point tracking opencv
WebJan 3, 2024 · To track the points, first, we need to find the points to be tracked. For finding the points, we’ll use cv2.goodFeaturesToTrack (). Now, we will capture the first frame and detect some corner points. These points will be tracked using the Lucas-Kanade Algorithm provided by OpenCV, i.e, cv2.calcOpticalFlowPyrLK (). Web2 days ago · I've built OpenCV 4.7 with CUDA support on Nvidia Jetson Xavier NX, is there any cv::Tracker* (or cv::legacy::Tracker*) algorithm implementation supporting CUDA/GPU processing? Almost all tracking implementations are very CPU intense, even after reducing frame size/rate.

To do this, we engineered an optimized neural net that uses 370x less … WebJan 8, 2013 · In this case the tracked 2d points will have the following structure, a vector of 2d points array, where each inner array represents a different frame. Every frame is composed by a list of 2d points which e.g. the first point in frame 1 is the same point in frame 2. If there is no point in a frame the assigned value will be (-1,-1):
If you look for a solution that is implemented in opencv the pyramidal Lucas Kanade (PLK) method is quit good, else I would prefer a Particle Filter based tracker. To improve your tracking performance with the PLK be sure that you have set up the parameters correctly.
