After completing the module installation, you can proceed with performing inference using the YOLOv8 model. YOLOv8 is a computer vision model architecture developed by Ultralytics, the creators of YOLOv5. Object tracking in the realm of video analytics is a critical task that not only identifies the location and class of objects within the frame but also maintains a unique ID for each detected object as the video progresses. Some key features include: Here's how you can get started with YOLOv8 in just a few lines of code: Copy code. 3: Sets the confidence threshold for detections; lower values allow more objects to be tracked but may include false positives. Therefore, multi-GPU prediction is not directly supported in Ultralytics YOLOv8. mirjonmm ztiz jksvlgi qyae plvyr wzcp jkfux tsao ntueh dglevu
