In this article will emphasize on some important characteristics and invariants with respect to transformations in projective geometry. Some properties in projective geometry The following properties are important to know if you want to work on stereo image processing, photogrammetry computer vision which contains 3D reconstruction, depth estimation and so on. For different dimensions in

As described in last article, projective space can be considered as a tool to mathematically describe the perspective projection. So in this article, we want to go through some basics, but important elements of projective space. After reading this article you will get to understand the followings topics: Homogeneous coordinates and its properties Homography matrix

I decided to write some short articles about projective geometry, and so these basics will give you not only some insight into the basics of stereo image processing but also help you understand linear transformations better. After reading this article you should be familiar with: Perspective Projection Perspective Space Projective Geometry and you should not
