MATCHING
IMAGES

The matching problem is to find corresponding points
between images when the imaging conditions
significantly change. We focus on the case when the resolution of
images is very different. 







Given corresponding couples of points we can determine
the transformation between two images.
If the images represent planar scenes we can estimate a 3x3 homography
matrix. In the case of 3D scenes
a 3x3 fundamental matrix can be computed using epipolar geometry
principles.

mouse pointer over the images below. 




To compute the transformation
matrix we need to establish several pointtopoint correspondences.
Stereo
Vision applet illustrates the problem and estimates the
transformation matrix.
