Singular Value Decomposition (SVD)

• Least Squares Solutions of nxn Systems-If A is ill-conditioned or singular,SVD can give usaworkable solution in this case too: x =A−1b ≈VD−1 0 U T b • Homogeneous Systems-Suppose b=0, then the linear system is called homogeneous: Ax =0 (assume A is mxn and A =UDVT)-The minimum-norm solution in this case isx=0 (trivial solution).

Image Projection - Department of Computer Science ...

CSC420: Image Projection Notes: 9. Example: The Horizon Line As another exercise in projective geometry, we consider multiple sets of parallel lines, all of which are coplanar in 3D. We show that the images of each parallel set of lines intersect and terminate at a point on the horizon line in the image.

CS231A Course Notes 1: Camera Models - Stanford University

Note that the projection of the object in the image plane and the image of the object in the virtual image plane are identical up to a scale (similarity) transformation. Now, how do we use pinhole cameras? Let P = x y z T be a point on some 3D object visible to the pinhole camera. Pwill be mapped or pro-jected onto the image plane 0, resulting ...

2 and the image point p, we can de ne the epipolar plane. With this epipolar plane, we can then determine the epipolar lines1. By de nition, P’s projection into the second image p0must be located on the epipolar line of the second image. Thus, a basic understanding of epipolar geometry allows us to create a strong constraint between image ...
