OpenCV in C# For Beginners - Introduction to Template Matching
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 discuss Template Matching in OpenCV! Template matching is a pretty cool way to do some basic object detection, and I use an example of a computer vision app that could visually grade a student's multiple choice test using OpenCV.
