Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of processing component images, the method comprising: accessing a first component image, the first component image being a spectral component image of at least an object and corresponding to a first spectral component, the object occupying a first portion of the first component image; accessing a second component image, the second component image being a spectral component image of at least the object and corresponding to a second spectral compon…
