Detecting a Drone - OpenCV in .NET for Beginners (Emgu CV 3.2, Visual Studio 2017). Part 2 2017-08-06

In Part 1 you have learned what OpenCV is, what is the role of Emgu CV wrapper and how to create a Visual Studio 2017 C# project that utilizes the two libraries. In this part I will show you how to loop through frames captured from video file. Check the first part to watch demo video and find information about sample project (all the interesting stuff is inside Program.cs - keep this file opened in separate tab as its fragments will be shown in this post)…

Setting Version of Assemblies in ASP.NET MVC Application With TeamCity Build Feature 2015-10-05

Last five posts (1, 2, 3, 4, 5) were all about fun stuff with Arduino. Now it’s time for something more mundane ;) In this post I will show you how to create TeamCity build that automatically sets version information in all assemblies produced by ASP.NET application. It’s nothing new but I hope to give you some useful background info and note a few gotchas you may face…
