Opencv for mac 2017 tutorial how to#

Mind that because Emgu CV/OpenCV binaries are quite large these are not included in the repo. It's a simple console app - I've put everything into Program.cs so you can't get lost! I plan to give detailed description of the whole program (don't worry: it's just about 200 lines) but if you would like to jump straight to the code visit this GitHub repository.

remove noise with erode and dilate (morphological operations).

find changes between images (diff and binary threshold).

use Emgu CV 3.2 in C# 7 (Visual Studio 2017) application (most tutorials available online are quite outdated!).I assume that you know a bit about C# programming, but are completely new to Emgu CV/OpenCV.īy the end of this tutorial, you will know how to: Job done! Oh, and if you are wondering what is the 'snow' seen in the video: these are some particles I put to make the video a bit more 'noisy'. The last frame shows the original frame with drone position marked. Next to it are various stages of image processing run before drone (contour) detection is executed. 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).

I'm far from computer vision expert but I know enough to teach you how to detect a mini quadcopter flying in a room: My experience with Emgu CV/OpenCV comes mostly from working on paintball turret project (which I use to have a break from 'boring' banking stuff at work).

The project was launched in 1999 by Intel Research and is now actively developed by open source community members and contributors from companies like Google, Microsoft or Honda. Open CV is written in highly optimized C/C++, supports multi-core execution and heterogeneous execution platforms (CPU, GPU, DSP.) thanks to OpenCL. NET wrapper for OpenCV (Open Source Computer Vision Library) which is a collection of over 2500 algorithms focused on real-time image processing and machine learning.
