The most important aspect of projective geometry is the introduction of homogeneous coordinates which represent a projective transformation as a matrix
Projective geometry models well the imaging process of a camera because it allows a much larger class of transformations than just translations
Computer Vision I. Projective geometry provides an elegant means for handling these different situations in a unified way and homogenous coordinates are a

In this appendix, we will briefly survey some basic concepts and properties of projective geometry which are extensively used in computer vision. For further
The interest of projective geometry arises in several visual comput- ing domains, in particular computer vision modelling and computer graphics. It provides a
