1. An image retoucher, comprising:
- a boundary detector adapted to detect a spurious boundary in a document image comprising a foreground and a background, detection being based, at least in part, upon information stored in a binary mask; and
, an image extender adapted to extend care pixels of at least one of the foreground and the background near the spurious boundary, extension being based at least in part, by alteration of the binary mask.

Abstract
A system and method facilitating image retouching is provided. The invention includes an image retoucher having a boundary detector and an image extender. The invention provides for the image retoucher to extend care pixels of at least one of a foreground and a background near a detected spurious boundary by altering the binary mask used for compression of the foreground and/or the background.

15. A method for retouching an image, comprising:
-
detecting a spurious boundary in a document image comprising a foreground and a background utilizing information stored in a binary mask; and
,extending care pixels of at least one of the foreground and the background near the spurious boundary by altering the binary mask, the altered binary mask being used for compressing at least one of the foreground and the background. - View Dependent Claims (16, 17, 18)

19. A segmented layered image system, comprising:
-
a mask separator adapted to assign pixels of a document image into at least one of a foreground and a background, the assignment information stored in a binary mask; and
,an image retoucher comprising a boundary detector adapted to detect a spurious boundary in the document image, detection being based, at least in part, upon information stored in the binary mask, the image retoucher further comprising an image extender adapted to extend care pixels of at least one of the foreground and the background near the spurious boundary, extension being based, at least in part, by alteration of the binary mask used for compression of at least on of the foreground and the background.
