This post shall discuss on a use case where we attempt to use object detection and tracking algorithm to check for obstruction within a specified zone in a video feed using OpenCV-Python. Long-term optical tracking is an important issue for many computer vision applications in real world scenario. Tags: BOOSTING C++ CSRT GOTURN KCL MEDIANFLOW MIL MOSSE object tracking OpenCV Python TLD. It begins with YOLOv8 object tracking to identify objects in video frames. The Kalman filter itself doesn't contain multiple object tracking machinery. init() function? is it (xcenter,ycenter,boxwidht,boxheight) or (xmin,ymin,xmax,ymax) or (ymin,xmin,ymax,xmax) or something completely different?. ny lm mc ak fp lf ol sh yo iu
