#001 OpenCV projects - Face Tracking with OpenCV using Haar cascade detectors

Highlights: This will be our introductory post where we will explain the difference between object detection and object tracking. We will learn the easiest way to track objects and in this case, it will be a face detection. We will admit that we are cheating a bit because we are not using tracking algorithms. Due to the simplicity of this post as a simple introduction, we are going to use Viola-Jones face detection algorithm. In one of our previous posts, we have already explained in detail what Haar cascade classifiers are and how to use them to detect faces, eyes, and smiles.
