In this post, we will learn the details of the Histogram of Oriented Gradients (HOG) feature descriptor. We will learn what is under the hood and how this descriptor is
This is a multipart post on image recognition and object detection. In this part, we will briefly explain image recognition using traditional computer vision techniques. I refer to techniques that
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
In this post I will explain how to find a crude approximation to the focal length of a webcam or cell phone camera ( i.e. fixed focal length cameras )
In this tutorial we will learn how to configure Qt to use OpenCV. Although the tutorial is targeted for OSX users, you can modify my suggestions for use in Linux
In this post I will share code for converting a 3×3 rotation matrix to Euler angles and vice-versa. 3D rotations matrices can make your head spin. I know it is
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
In this tutorial we will see how to warp a single triangle in an image to another triangle in a different image. In computer graphics people deal with warping triangles
In this tutorial we will learn how to create an average face using OpenCV ( C++ / Python ). Most people would agree that the woman in Figure 1 is
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. Ladies and
