Contours and Edge Detection with OpenCV in C#
In this series, I will be taking you through an introductory tour of OpenCV and Emgu (the OpenCV C# Wrapper)!
OpenCV has been one of my favorite libraries to tinker with, where you can do some impressive things such as facial recognition, image manipulations and filters, video processing, and much more! So I wanted to introduce fellow programmers to it, so you can have as much fun as I’ve had over the years.

In this video, I go over two Edge Detection functions in OpenCV, Sobel operation and Canny Edge Detection, as well as how Contours work, how to draw Contours onto your image, and even how to fill in some color into the area defined by the contour, which results in changing the color of our object!
