retargeting algorithms attempt to adapt the image content
to the screen without distorting the important objects in the scene.
methods address retargeting of a single image. In this paper we propose
method for retargeting a pair of stereo images. Naively retargeting
independently will distort the geometric structure and make it
perceive the 3D structure of the scene. We show how to extend a single
seam carving to work on a pair of images. Our method minimizes the
distortion in each of the images as well as the depth distortion. A key
property of the proposed method is that it takes into account the
relations between pixels in the image pair (occluded and occluding
a result, our method guarantees, as we formally prove, that the
is geometrically consistent with a feasible 3D scene, similar to the
one. Hence, the retargeted stereo pair can be viewed on a stereoscopic
or processed by any computer vision algorithm. We demonstrate
on a number of challenging indoor and outdoor stereo images.
