Abstract
A content editor application receives a reference map that indicates which portions of a first image are foreground, and which portions of the first image are background. The content editor compares a coloration of regions in the first image to a coloration of regions in the second image. For regions in the second image that match a coloration of corresponding regions in the first image, or that are within a threshold range of coloration, the content editor uses the reference map to mark regions of the second image that are foreground and to mark which regions of the second image are background. Accordingly, the reference map of the first image can be used to identify whether regions of a second image or subsequent images in a sequence are foreground and which are background.
