Image retargeting algorithms often create visually disturbing
distortion. We introduce the property of scene consistency, which
is held by images which contain no object distortion and have the correct
object depth ordering. We present two new image retargeting algorithms
that preserve scene consistency. These algorithms make use of a
user-provided relative depth map, which can be created easily using a
simple GrabCut-style interface. Our algorithms generalize seam carving.
We decompose the image retargeting procedure into (a) removing image
content with minimal distortion and (b) re-arrangement of known
objects within the scene to maximize their visibility. Our algorithms optimize
objectives (a) and (b) jointly. However, they differ considerably
in how they achieve this. We discuss this in detail and present examples
illustrating the rationale of preserving scene consistency in retargeting.
