Registration of Separations

A method of performing registration of digitized images, the method comprising:

• selecting a first area in each of a first image and a second image;
• determining which pixels in the first areas of the first and second images are feature pixels;
• comparing the first areas of the first and second images by weighting (a) a comparison of feature pixels in the first area of the first image with corresponding pixels in the first area of the second image differently than (b) a comparison of non-feature pixels in the first area of the first image with corresponding pixels in the first area of the second image;
• and
• determining a transformation for the first area of the first image based on the comparison of the first areas of the first and second images.

A method of performing registration of digitized images, the method comprising:

• selecting a first area from each of a first image and a second image;
• detecting a first set of features in the first area of the first image;
• determining a second set of features consisting of the features from within the first set that include a first predetermined amount of information;
• determining whether the second set of features is collectively sufficient to provide a meaningful comparison;
• and
• determining, if the second set of features is deemed collectively sufficient, a transformation for the first area of the first image based on a comparison of the first area of the first image with areas of the second image.

A method of performing registration of digitized images, the method comprising:

• selecting automatically a first area in each of a first image and a second image;
• determining automatically a transformation for the first area in the first image based on a comparison of the first area of the first image with corresponding areas of the second image;
• and
• applying automatically the transformation to the first area in the first image, wherein a film distortion is reduced.
