System Requirement

Component Requirement Detail
Emgu CV Version 2.0.1.0 Available only from SVN
Operation System Cross Platform

Source Code

<source lang="csharp">

  1. region generate random points

System.Random r = new Random(); int sampleCount = 100; Ellipse modelEllipse = new Ellipse(new PointF(200, 200), new SizeF(90, 60), -60); PointF[] pts = PointCollection.GeneratePointCloud(modelEllipse, sampleCount);

  1. endregion

Stopwatch watch = Stopwatch.StartNew(); MCvBox2D box = PointCollection.MinAreaRect(pts); watch.Stop();

  1. region draw the points and the box

Image<Bgr, byte> img = new Image<Bgr, byte>(400, 400, new Bgr(Color.White)); img.Draw(box, new Bgr(Color.Red), 1); foreach (PointF p in pts)

  img.Draw(new CircleF(p, 2), new Bgr(Color.Green), 1);
  1. endregion

ImageViewer.Show(img, String.Format("Time used: {0} milliseconds", watch.ElapsedMilliseconds));</source>

Result
