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…

Highlights: Hello and welcome to our new post. In this lecture, we will continue gaining a good understanding of the image formation process. In particular, we are going to talk about how we can project a 3D scene onto a 2D image. We will introduce basic primitives and transformations in conventional but also in so-called homogeneous coordinates which play a fundamental role in describing objects and projections in 3D computer vision. Once we have an…

Highlight: Hi and welcome to our new post! In this post, we will continue our journey of understanding how fundamental computer vision techniques work. We first need to understand how images are formed, and how to go from a 3D scene to a 2D image. By understanding this we can develop models that mathematically formalize this process. So, let us start. Understanding what are primitives They represent the basic building blocks that are used to…

Highlights: Hello, and welcome. In this post, we’re going to talk about how to form an image from a 3D scene onto a 2D plane. We will start with a concept of a pinhole camera which is one of the most important concepts in computer vision. It is the simplest type of camera that you can imagine and it performs perspective projection. In this post, we are going to review the YouTube video “Pinhole and…

Highlights: Hello and welcome back! We will continue our post series on talking faces. In this post, we will explore, the so-called, face animation. That is, we will not be focussed on face photo-realism, but on a digital avatar. So, let’s begin. Let’s have a look at the image below. Here we can see the difference between the animated character and a realistic 3D digital human. In this post, we will explore a model called…
