In general, the system and method of the present invention computes 2D projective transforms or homographies derived from specialized projective and affine transforms or components. The affine transform is comprised of a first transform and an optional second transform for image rectification. During image rectification of the present invention, optimization techniques are used for reducing the distortion.Other References
