#007 Advanced Computer Vision – Video Stabilization

19.01.2023

Highlights: Hello and welcome. In this post[1], we will learn to remove unwanted camera movement or shake from a video using a technique called Video stabilization. It is typically used to make videos appear smoother and more professional. There are a variety of techniques that can be used to stabilize a video, including image cropping, image scaling, and frame-by-frame motion estimation. In this post, we will present an efficient and robust implementation of a digital…

#027 R-CNN, Fast R-CNN, and Faster R-CNN explained with a demonstration in PyTorch

16.01.2023

Highlights: Object detection is one of the most important tasks in Computer Vision. In this post, we will give an overview of one of the most influential families of object detection algorithms: R-CNN, Fast R-CNN, and Faster R-CNN. We will highlight the main novelties and improvements for each of them.  Finally, we will focus on the Faster R-CNN and explore the code and how it can be used in PyTorch.  Tutorial Overview: 1. Introduction to…

#016 3D Face Modeling – Linear camera model

30.12.2022

Highlight: In this post, we are going to talk about what calibration is and how it is performed. Calibration represents the process of going from one coordinate system to another, for example going from meters to pixels. We will explain how an image is formed, in more detail, how we go from the 3D scene in the real world to the 2D image plane in the camera. In this post, we are going to review…

#015 3D Face Modeling – The geometric image formation

30.12.2022

Highlight: In this post, we are going to talk about the geometric image formation process and some basic camera models. We will explain in detail how 3D points/lines are projected in 2D planes. How it all started. Inside an entirely dark room that had only one little pinhole in the door, the outside scenes and objects were projected upside down onto the dark wall. This was due to the illumination of the light that was…

#013 3D Face Modeling – Creating a 3D model of a cube from one image

30.12.2022

Highlights: Hello, and welcome. In this post, we’re going to talk about how we can create a 3D model of a cube with only one image as input. The way we are going to achieve this is the same as we explained previously for the 3D face model. So let us begin! 1. Creating 3D cubes The first step we need to do is to create different 3D cubes to replicate a database of 3D…
