1. A method for automatically registering color components of a color film, the method comprising the steps of: downsampling, from a desired resolution to a lower resolution, image data of the color components of the color film to be registered to speed up processing; determining correlation data between the color components of the color film; processing the correlation data; upscaling matched displacement vectors to the desired resolution before combining is performed; determining Affine Transform parameters for the color components; calculating the Affine Transform for each pixel in the respective color component using the determined parameters; and combining the color components to re-produce the color film.
