StrongSort.Net

CI NuGet License: MIT .NET

Pure C# implementation of StrongSORT ("StrongSORT: Make DeepSORT Great Again") — a multi-object tracker combining an NSA Kalman filter, EMA-smoothed appearance embeddings and Hungarian assignment. No native or ML dependencies: bring your own detector and (optionally) ReID embeddings.

This is an independent, clean-room implementation written from the published algorithm; it is not affiliated with the original authors.

Install

dotnet add package StrongSort.Net

Usage

using StrongSort;

var tracker = new StrongSortTracker(new StrongSortOptions
{
    MaxAppearanceDistance = 0.5f,
    MaxAge = 300,
});

foreach (var frame in video)
{
    var observations = detector.Detect(frame)
        .Select(d => new Observation(d.Left, d.Top, d.Width, d.Height, d.Confidence,
                                     Feature: reid.Embed(frame, d), Tag: d.Id));
    IReadOnlyList<TrackResult> tracks = tracker.Update(observations.ToList());
    // tracks: stable TrackId, Kalman-smoothed BboxLtwh, Tag of the matched observation
}
  • Works without embeddings too (Feature: null) — matching then falls back to the IoU stage.
  • Tag is an arbitrary payload (e.g. your detection id) returned on the matched track.
  • Defaults follow the SoccerNet game-state baseline; original paper defaults are documented on StrongSortOptions.
