REGISTRATION OF SEPARATIONS
First Claim
1. A method of performing registration of digitized images, the method comprising:
- dividing a selected component image into a set of areas;
grouping the areas into multiple rings; and
determining transformations for at least two areas in the set of areas in an order that begins with at least one area within an innermost ring and proceeds to at least one area within a ring other than the innermost ring.

Abstract
Separations or images relating to film or other fields may be registered using a variety of features, such as, for example: (1) correcting one or more film distortions; (2) automatically determining a transformation to reduce a film distortion; (3) applying multiple criteria of merit to a set of features to determine a set of features to use in determining a transformation; (4) determining transformations for areas in an image or a separation in a radial order; (5) comparing areas in images or separations by weighting feature pixels differently than non-feature pixels; (6) determining distortion values for transformations by applying a partial distortion measure and/or using a spiral search configuration; (7) determining transformations by using different sets of features to determine corresponding transformation parameters in an iterative manner; and (8) applying a feathering technique to neighboring areas within an image or separation.

6. A computer program for performing registration of digitized images, the computer program residing on a computer-readable medium and comprising instructions for causing a computer to perform operations including:
-
dividing a selected component image into a set of areas;
grouping the areas into multiple rings; and
determining transformations for at least two areas in the set of areas in an order that begins with at least one area within an innermost ring and proceeds to at least one area within a ring other than the innermost ring.

7. A method of performing registration of digitized images, the method comprising:
-
dividing a selected component image into a set of areas; and
determining a transformation for a particular area in the set of areas based on at least one previously determined transformation for at least one other area, where a center of the other area is not farther in proximity to a center of the selected component image than is a center of the particular area. - View Dependent Claims (8, 9)
