Abstract
A method for color correcting imagery is disclosed. A plurality of images of a scene having different levels of detail is received. A first color correction is determined based on a first reference image and a first target image. The first reference image has a first level of detail and the first target image has a second level of detail greater than the first level of detail. The first color correction is applied to the first target image to generate a first color-corrected image having the second level of detail. A second color correction is determined based on the first color-corrected image and a second target image. The second target image has a third level of detail greater than the second level of detail. The second color correction is applied to the second target image to generate a second color-corrected image.
