Highlights: Today you can find countless numbers of photo editing applications on the internet that allows you to transform your images into cartoons on the internet. This pretty cool effect became extremely popular on social media over the past few years. That is why we decided to teach you how to use OpenCV to create your application that can transform an image into a cartoon. To do that we will be working with digital image…

Highlights: In this post, we are going to have some fun. We will apply Haar cascade classifiers to detect faces, and different parts of the face in a video such as eyes, and mouth. Then, we will learn how to place funny objects like masks, mustaches, or glasses over the detected part of a face. Tutorial overview: Introduction How to put a mask over the face? How to put a mustache over the face? How…

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…

Highlights: In this post, we are going to show how to detect distinct features in an image. We will describe the important properties of these features (keypoints) and we will learn how we can use them to better understand the structure and the content of an image. Furthermore, we will talk about the most common algorithms that can be used for feature detection. So, let’s begin. Tutorial overview: What are keypoints? Detecting corners with Harris…
