OpenCV lets you write software for:. The project was launched in by Intel Research and is now actively developed by open source community members tutoroal contributors from companies like Google, Microsoft or Honda I’m far from computer vision expert but I know enough to teach you how to detect a mini quadcopter flying in a room:.
In the upper-left corner, you can see frame captured from video file, following that is the background frame static background and camera makes our task simpler Next to it are various stages of image processing run before drone contour detection is executed.
The last frame shows the original frame with drone position marked. Oh, and if you are wondering what is the “snow” seen in the video: I plan to give detailed description of the whole program don’t worry: It’s a simple console app – I’ve put everything into Program. This should not be a problem because Visual Studio should be able to automatically download restore the packages Here you can download the video I’ve used for testing: Now we need to add Emgu CV to our project.

If you are curious, read this nice description of Mat. The other interesting thing you can see in the code is the CvInvoke class.
You can use it to call OpenCV functions from your C application without dealing with complexity of operating native code and data structures from managed code – Emgu the wrapper will do it for you through PInvoke mechanism.
