Beschreibung

This lecture covers advanced topics in the field of computer vision and computer graphics. It will be given in English. The target audience are students in computer science or related fields. Basic knowledge about 3D geometry, image processing, and computer graphics is beneficial. In order to be admitted to the final oral exam at the end of the semester, five homework assignments must be passed.

The lecture is structured as follows:

1. Scene representation
   • Scene elements: lighting, geometry, cameras
   • Basic animations
   • Homework: Generate your own animated scene using Collada
2. The history of visual special effects
   • Visual illusions
   • Matte painting
3. Advanced camera models
   • Finite cameras
   • Projective cameras
   • Affine cameras
   • Other cameras
   • Lens distortions
   • Homework: Camera matrix decomposition
4. Foundations of camera motion estimation
   • Feature detection
   • Feature tracking
   • 2D homography
   • Fundamental matrix
   • Trifocal tensor
   • Applications
5. Camera motion estimation
   • N-view approaches
   • (Sparse) bundle adjustment
   • Self calibration
   • Applications
