Neither the class nor the exercises require any registration.

Homeworks

We will announce special dates on which students have to show their homework either on their own computer or on the computers of the CAMP-Lab. In these sessions, we will check the latest 3-5 homeworks.

Matlab

In order to do the exercises students must know how to program in Matlab. A basic introduction is given on April 22nd from 14:30-16:00 in MI 03.13.010. The time of the exercise is a SINGLE EXCEPTION since it is hold jointly with the CAMP lecture. The regular time of the exercises is each Thursday between 12:30-14:00. Please read the Matlab tutorial/sheet given under Exercises if you want to attend!

Overview

Making a computer see was something that leading experts in the field of Artificial Intelligence thought to be at the level of difficulty of a summer student's project back in the sixties. Forty years later the task is still unsolved and seems formidable. A whole field, called Computer Vision, has emerged as a discipline in itself with strong connections to mathematics and computer science and looser connections to physics, the psychology of perception and the neuro sciences.

Over the past decade there has been a rapid development in the understanding and modeling of the geometry of multiple views in computer vision. The theory and practice have now reached a level of maturity where excellent results can be achieved for problems that were unsolved a decade ago, and often thought unsolvable. These tasks and algorithms include problems like:
Given two/three/multiple images, and no further information, compute/estimate:

  • matches between the images
  • the 3D position of the points that generate these matches
  • the cameras that generate the images

(Adapted form Hartley & Zisserman's "Multiple View Geometry in Computer Vision")

The fundamental mathematics and a profound comprehension of the basics of projective geometry as well as one-view geometry are the core of the lecture 3D Computer Vision.
