SORT
Simple Online and Realtime Tracking (arXiv 1602.00763). Pairs a Kalman filter with greedy IoU matching. Built for speed; best when objects rarely overlap.

fn main() {
use trackforge::trackers::sort::Sort;
let mut tracker = Sort::new(1, 3, 0.3);
let tracks = tracker.update(vec![([100.0, 100.0, 50.0, 100.0], 0.9, 0)]);

}Parameters
| Parameter | Default | Description |
|---|---|---|
max_age | 1 | Frames to keep a track alive without a detection match |
min_hits | 3 | Consecutive matched frames before a track is confirmed |
iou_threshold | 0.3 | Minimum IoU to associate a detection with a track |
Tuning: raise max_age to bridge short occlusions (at the cost of more false tracks); lower
iou_threshold for densely packed objects; raise min_hits to suppress false starts from a noisy
detector.
