trackforge 0.3.0

A unified, high-performance computer vision tracking library.

Trackforge is a unified, high-performance computer vision tracking library implemented in Rust with Python bindings. It provides real-time multi-object tracking algorithms, optimized for speed and designed as the CPU "glue" between GPU-based object detectors and your tracking pipeline.

Supported Trackers

Tracker	Type	Appearance (Re-ID)
ByteTrack	IoU + confidence association	No
DeepSORT	IoU + cosine distance	Yes (pluggable)
OC-SORT	IoU + velocity direction (OCM)	No
SORT	IoU + Kalman filter	No

Features

• 🚀 Native Rust Core Blazingly fast tracking (< 1ms/frame for ByteTrack) with full memory safety
• 🐍 Python Bindings First-class pip install trackforge support via PyO3
• 🎯 Multi-Algorithm ByteTrack, OC-SORT, DeepSORT, and SORT with a unified API
• 🔌 Pluggable Re-ID DeepSORT's appearance extractor is a trait; plug in any feature model
• 📐 Generic Kalman Filter Configurable position/velocity weighting, gating distance computation

[!IMPORTANT] Under active development. APIs and features are subject to change. MSRV: Rust 1.89.

Installation

Python

pip install trackforge

Rust

Add to your Cargo.toml:

[dependencies]
trackforge = "0.3.0"

To build the Python bindings from source (e.g. via maturin develop), enable the python feature:

[dependencies]
trackforge = { version = "0.3.0", features = ["python"] }

Quick Start

Python - ByteTrack

from trackforge import BYTETRACK

tracker = BYTETRACK(track_thresh=0.5, track_buffer=30, match_thresh=0.8, det_thresh=0.6)

# Format: ([x, y, w, h], confidence, class_id)
detections = [
    ([100.0, 100.0, 50.0, 100.0], 0.9, 0),
    ([200.0, 200.0, 60.0, 120.0], 0.85, 0),
]

tracks = tracker.update(detections)

for track_id, tlwh, score, class_id in tracks:
    print(f"ID: {track_id}, Box: {tlwh}")

Python - DeepSORT

from trackforge import DEEPSORT

tracker = DEEPSORT(
    max_age=30,
    n_init=3,
    max_iou_distance=0.7,
    max_cosine_distance=0.2,
    nn_budget=100,
)

detections = [([100.0, 100.0, 50.0, 100.0], 0.9, 0)]
embeddings = [[0.1, 0.2, 0.3, ...]]  # appearance feature vectors

tracks = tracker.update(detections, embeddings)

for track_id, tlwh, score, class_id in tracks:
    print(f"ID: {track_id}, Box: {tlwh}, Score: {score}")

Python - OC-SORT

from trackforge import OCSORT

tracker = OCSORT(
    max_age=30,
    min_hits=3,
    iou_threshold=0.3,
    delta_t=3,
    inertia=0.2,
)

detections = [
    ([100.0, 100.0, 50.0, 100.0], 0.9, 0),
    ([200.0, 200.0, 60.0, 120.0], 0.85, 0),
]

tracks = tracker.update(detections)

for track_id, tlwh, score, class_id in tracks:
    print(f"ID: {track_id}, Box: {tlwh}")

Rust - ByteTrack

use trackforge::trackers::byte_track::ByteTrack;

let mut tracker = ByteTrack::new(0.5, 30, 0.8, 0.6);

// Format: ([x, y, w, h], confidence, class_id)
let detections = vec![
    ([100.0, 100.0, 50.0, 100.0], 0.9, 0),
    ([200.0, 200.0, 60.0, 120.0], 0.85, 0),
];

let tracks = tracker.update(detections);

for t in tracks {
    println!("ID: {}, Box: {:?}", t.track_id, t.tlwh);
}

Rust - DeepSORT

use trackforge::trackers::deepsort::DeepSort;

// `extractor` implements the AppearanceExtractor trait (plug in any Re-ID model).
let mut tracker = DeepSort::new(extractor, 30, 3, 0.7, 0.2, 100);

let detections = vec![(BoundingBox::new(100.0, 100.0, 50.0, 100.0), 0.9, 0)];
let tracks = tracker.update(&image, detections)?;

for t in tracks {
    println!("ID: {}, Box: {:?}", t.track_id, t.to_tlwh());
}

Rust - OC-SORT

use trackforge::trackers::ocsort::OcSort;

let mut tracker = OcSort::new(30, 3, 0.3, 3, 0.2);

let detections = vec![
    ([100.0, 100.0, 50.0, 100.0], 0.9, 0),
    ([200.0, 200.0, 60.0, 120.0], 0.85, 0),
];

let tracks = tracker.update(detections);

for t in tracks {
    println!("ID: {}, Box: {:?}", t.track_id, t.tlwh);
}

Rust - SORT

use trackforge::trackers::sort::Sort;

let mut tracker = Sort::new(1, 3, 0.3);

let detections = vec![([100.0, 100.0, 50.0, 100.0], 0.9, 0)];
let tracks = tracker.update(detections);

for t in tracks {
    println!("ID: {}, Box: {:?}", t.track_id, t.tlwh);
}

Examples

Runnable demos live under examples/, with both a Python and a Rust entry per tracker.

Tracker	Python	Rust
ByteTrack	byte_track_demo.py (YOLO11)	byte_track_demo.rs
DeepSORT	deepsort_demo.py (YOLO + ResNet18)	deepsort_simple.rs, deepsort_ort.rs (ONNX)
OC-SORT	ocsort_demo.py	—
SORT	sort_yolo_demo.py (YOLO), sort_rtdetr_demo.py (RT-DETR)	—
All four	tracker_comparison.py side-by-side benchmark	—

# Python
python examples/python/byte_track_demo.py

# Rust
cargo run --example byte_track_demo
cargo run --example deepsort_simple
cargo run --example deepsort_ort --features advanced_examples

The Python demos use the usual detector stacks: ultralytics (YOLO), transformers + torch (RT-DETR), and torch + torchvision (ResNet Re-ID); install what a given demo imports. The deepsort_ort Rust demo needs the advanced_examples feature (ONNX Runtime + OpenCV).

API Reference

Parameters

Each tracker's parameters and defaults (identical across Python and Rust) are documented on the Parameters page.

Development

Prerequisites

• Rust 1.89+ (MSRV)
• Python 3.8+ and maturin for the bindings
• prek for git hooks (optional but recommended)

Setup

git clone https://github.com/onuralpszr/trackforge.git
cd trackforge

# Rust core
cargo build
cargo test

# Python bindings (build into the active virtualenv)
maturin develop

Checks

These mirror CI, run them before opening a PR:

cargo fmt --all -- --check          # formatting
cargo clippy --all-targets -- -D warnings   # lint, warnings are errors
cargo test                          # unit, integration, and doc tests
cargo llvm-cov --summary-only       # coverage (cargo install cargo-llvm-cov)
prek run --all-files                # all pre-commit hooks at once

Feature flags

• python builds the PyO3 bindings.
• advanced_examples enables the ONNX/OpenCV-backed examples (deepsort_ort), which need ONNX Runtime and OpenCV on the system.

cargo test --features python
cargo run --example deepsort_ort --features advanced_examples

Run a Python example

# After `maturin develop`:
python examples/python/deepsort_demo.py --video your_video.mp4

Contributing

Contributions are welcome! Please see CONTRIBUTING.md for guidelines.

• For major changes, open an issue first to discuss what you would like to change.
• PRs should pass CI: cargo fmt, cargo clippy -- -D warnings, cargo test.
• Use Commitizen for commit messages: cz commit.
