Summary:
The course focuses on the geometric aspects of computer vision: the geometry of
image formation and its use for 3D reconstruction and calibration. The objective
of the course is to introduce the formal tools and results that are necessary
for developing multi-view reconstruction algorithms. The fundamental tools
introduced study affine and projective geometry, which are essential to the
development of image formation models. Additional algebraic tools, such as
exterior algebras are also introduced at the beginning of the course. These
tools are then used to develop formal models of geometric image formation for a
single view (camera model), two views (fundamental matrix), and three views
(trifocal tensor); 3D reconstruction from multiple images; and auto-calibration.
If time permits, we will also look at the application of these concepts to the reconstruction of smooth surfaces.
Administration:
The evaluation is based on a midterm, final exam, and projects, as well as class participation.
