#009 How to detect facial landmarks using DLIB and OpenCV

10.06.2020

Highlight: In this post you are going to learn how to detect facial landmarks in an image using dlib and OpenCV. This knowledge will be useful, since facial landmarks are the key features in a large number of facial analysis methods and algorithms. Face recognition, face alignment, facial expression recognition, face swapping, drowsiness detection, blink detection, head pose estimation, are the few examples in which facial landmarks play a fundamental role. let us see what…

# 008 How to detect faces, eyes and smiles using Haar Cascade Classifiers with OpenCV in Python

10.06.2020

Highlights: If you have any type of camera that does face detection it is probably using Haar feature-based cascade classifier for object detection. In this post we are going to learn what are these Haar cascade classifiers and how to use them to detect faces, eyes and smiles. Tutorial Overview: Understanding Haar cascade classifiers How to detect faces, eyes and smiles with Haar cascade classifiers? 1. Understanding Haar Cascade Classifiers Two decades ago, face detection…

#006 Morphological transformations with OpenCV in Python

10.06.2020

Highlight: In this OpenCV with Python post we are going to talk about morphological transformations. Fundamentally, there are two basic morphological transformations and they are called dilation and erosion. They are present in image processing in different applications. They are used for the removal of noise or for finding the bumps or holes in images. In addition, these operations can also be used to calculate gradients of images. Moreover, once we learn two basic morphological…

#007 Color quantization using K-means clustering

10.06.2020

Highlight: This post can come as a very interesting and surprising one. You will see how we can apply a machine learning algorithm on the pixel intensity color with a so-called K-means clustering algorithm. In this way, we would be able to create a compressed version of our image that will have much fewer colors. The picture will be preserved in a lower color resolution, whereas the number of pixels will remain the same. This…
