"iou": ["float", "0.5", "Sets the Intersection over Union (IoU) threshold for filtering overlapping detections."],

"verbose": ["bool", "True", "Controls the display of tracking results, providing a visual output of tracked objects."],

"show": ["bool", "False", "If True, displays the annotated images or videos in a window for immediate visual feedback."],
"line_width": ["None or int", "None", "Specifies the line width of bounding boxes. If None, the line width is automatically adjusted based on the image size."]
