Exemplary methods for estimating an orientation angle and a translation
values for scanned images are disclosed. The methods described herein may
be embodied as logic instructions on a computer-readable medium. In one
exemplary implementation meaningful image information is removed from a
scanned image, resulting in a transformed image that comprises
alternating, parallel lines disposed at an orientation angle relative to
an orthogonal axis. The orientation angle may be determined using
geometric techniques or statistical correlation techniques, and
statistical correlation techniques may be implemented to determine
translation values.
