Drawing the contour of the particles found by ParticleReport

[Jürgen Cramer]

I use Vision Module 2009 for .NET and c#

My question is how I can draw the contour of a particle found by the ParticleReport(). I tried GetPointsOnContour() but this delivers not the complete outline.

Furthermore I want to use this particle as a ROI for further operation.

Thanks for your assistance.

The same problem is addressed for LabVIEW here:

However,  you are using.NET. Luckily, the same concepts still apply. Instead of the LabVIEW VI "IMAQ MaskToROI", you should use the method MaskToRegions.

This is exactly what I am looking for. But in .NET the algorithm is also MaskToROI().
