.Net library which is compatible with EmguCV for ellipse detection based on the algorithm of very fast ellipse detector, codename: YAED (Yet Another Ellipse Detector). This library is modified based on EllipseDetectorLib

It uses:

• Emgu CV

• Open Source Computer Vision Library

for image reading and processing.

Real-time ellipse detection is an important yet challenging task, since the estimation of the five parameters of an ellipse requires heavy computation.

A new efficient ellipse detection method (Y. Xie and Q. Ji) has remained ineffective and inappropriate for realtime processing.

This library is suitable in programs which require an approximate ellipse detection and have to do this in realtime.

There are two projects:

• EmguCvEllipseDetector: the main C++/CLI .Net library. In other words this is the wrapper.

• TestCSharp: the example written in C# which uses EmguCvEllipseDetector library.

This library has been written in Microsoft Visual Studio 2017. Files .csproj contain configurations for platforms x64 with both Debug and Release modes. For successfull build OpenCV and EmguCV have to be installed. In addition environment variable OPENCV_DIR where opencv is installed should be set. To run the test program, opencv_world**.dll needs to be manually copied to the bin directory.

Here are just a few examples of what EllipseDetectorLib can do:

• Samples: A dozen files shows the initial and result images.
