Registration of separations
First Claim
1. A method of processing component images, the method comprising:
- accessing a first component image, the first component image being a digital color component image of a scene and corresponding to a first color;
accessing a second component image that is separate from the first component image, the second component image being a digital color component image of the scene and corresponding to a second color that is different than the first color;
accessing a third component image that is separate from the first component image and the second component image, the third component image being a digital color component image of the scene and corresponding to a third color that is different than the first color and the second color;
transforming the first component image, the second component image, and the third component image to generate a transformed version of the first component image, a transformed version of the second component image, and a transformed version of the third component image;
aligning the transformed version of the first component image, the transformed version of the second component image, and the transformed version of the third component image; and
based on the alignment of the transformed version of the first component image, the transformed version of the second component image, and the transformed version of the third component image, recombining, by at least one processor, the transformed version of the first component image, the transformed version of the second component image, and the transformed version of the third component image into a composite color image of the scene.

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.
