Registration of separations
First Claim
1. A method of processing images of film stock, the method comprising:
- accessing a first image of film stock bearing a first photograph;
accessing a second image of film stock bearing a second photograph that is different than the first photograph;
identifying a particular set of one or more features in (i) a first portion of the first image, and (ii) a second portion of the second image;
transforming at least a portion of the second image to generate a transformed version of the second image, wherein the particular set of one or more features are located in a third portion of the transformed version of the second image;
aligning the transformed version of the second image and the first image;
combining the first image and the transformed version of the second image into a composite image; and
storing the composite image and one or more other images on a non-transitory machine-readable medium as a set of images, the set of images representing frames of a motion picture.

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.

15. A non-transitory computer-readable medium storing instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
-
accessing a first image of film stock bearing a first photograph; accessing a second image of film stock bearing a second photograph that is different than the first photograph; identifying a particular set of one or more features in (i) a first portion of the first image, and (ii) a second portion of the second image; transforming at least a portion of the second image to generate a transformed version of the second image, wherein the particular set of one or more features are located in a third portion of the transformed version of the second image; aligning the transformed version of the second image and the first image; combining the first image and the transformed version of the second image into a composite image; and storing the composite image and one or more other images on a non-transitory machine-readable medium as a set of images, the set of images representing frames of a motion picture. - View Dependent Claims (16, 17, 18)

19. A method of processing images of film stock, the method comprising:
-
accessing one or more component images that are based on digitized film separations, wherein each of the one or more component images includes a set of gray-level pixels; selecting an image from the one or more component images; determining an alignment vector for at least a part of the selected component image; and applying the alignment vector to the part of the selected component image to correct one or more film distortions. - View Dependent Claims (20)
