Facemark : Facial Landmark Detection using OpenCV
In this tutorial, we will learn about facial landmark detection using OpenCV with no external dependencies. I have written several posts about Facial Landmark Detection and its applications. You can use landmark detection for face morphing, face averaging and face swapping. Until now, we had used the landmark detection that comes with Dlib. It works […]

Face Morph Using OpenCV — C++ / Python
In this tutorial we will learn how to morph one face into another using OpenCV. I have chosen to use the photos of the top three American Presidential candidates, but this is not a political post and I have no political agenda. And yes, that is the prettiest picture of Donald Trump I could […]

Face Swap using OpenCV ( C++ / Python )
In this tutorial we will learn how to swap out a face in one image with a completely different face using OpenCV and DLib in C++ and Python. To understand the description below better, download the C++ and Python code and images by subscribing to our newsletter here. Ladies and gentlemen, let me present Ted Trump, […]

Speeding up Dlib’s Facial Landmark Detector
In this tutorial I will explore a few ways to speed up Dlib’s Facial Landmark Detector. Dlib’s Facial Landmark Detector Dlib has a very good implementation of a very fast facial landmark detector. I had reviewed it in my post titled Facial Landmark Detection. Subsequently, I wrote a series of posts that utilize Dlib’s facial […]

Head Pose Estimation using OpenCV and Dlib
In this tutorial we will learn how to estimate the pose of a human head in a photo using OpenCV and Dlib. In many applications, we need to know how the head is tilted with respect to a camera. In a virtual reality application, for example, one can use the pose of the head to […]

Automatic Red Eye Remover using OpenCV (C++ / Python)
In this tutorial, we will learn how to remove red eyes from a photo completely automatically. Just thinking about this problem of red-eye removal brings back memories from my childhood. I grew up in small towns in India where not every family in my middle-class neighborhood had a camera. My family owned a point-and-shoot color […]

Gender & Age Classification using OpenCV Deep Learning ( C++/Python )
In this tutorial, we will discuss an interesting application of Deep Learning applied to faces. We will estimate the age and figure out the gender of the person from a single image. The model is trained by Gil Levi and Tal Hassner. We will discuss in brief the main ideas from the paper and provide […]

Face Recognition: An Introduction for Beginners
Face Recognition is a computer vision technique which enables a computer to predict the identity of a person from an image. This is a multi-part series on face recognition. In this post, we will get a 30,000 feet view of how face recognition works. We will not go into the details of any particular algorithm, […]

Using Facial Landmarks for Overlaying Faces with Masks
Have you ever wondered how Instagram masks are fitting so perfectly on your face? Would you like to know how you can try to implement something similar by yourself? This post will help you with that! To remind you how important it is to wear a medical mask in the current COVID-19 pandemic, we will […]

Face Recognition with ArcFace
Can we distinguish one person from another by looking at the face? We can probably list several features such as eye colour, hairstyle, skin tone, the shape of nose and eyebrows, etc. Some combination of such attributes will be unique to a particular person. Sometimes, people have visual similarities, and in rare cases, it becomes […]
