1. New sensing technologies: 3D time-of-fight cameras and Fourier-slice photography with plenoptic cameras
   The 3D cameras measure the distance to objects by measuring the time it takes the emitted light to return from the reflecting object. I will present the basic principle and briefly the technological state of the art. Plenoptic cameras have one main lens for image formation and an array of microlenses in front of the image sensor. By this optical design, the cameras record light fields. We will understand the mathematical principles of Fourier-slice photography: a conventional image is a 2D cut in the 4D Fourier transform of the 4D light field. Different cuts correspond to different depth planes.

2. Human and augmented vision
   The scope of this lecture is to learn about the basic principles of visual information processing. Why learn that?
   - Because the technical systems that we build today are much too simple relative to the complexity of the biological system they are build for (technical design must be more human centered).
   - Learn about ways of building machine-vision systems.
