Depth-Aware Stereo Video Retargeting

Bing Li, Chia-Wen Lin, Boxin Shi, Tiejun Huang, Wen Gao, C.-C. Jay Kuo

The proposed depth-aware retargeting method reconstructs the 3D scene to obtain the depth information of salient objects.  ...  As compared with traditional video retargeting, stereo video retargeting poses new challenges because stereo video contains the depth information of salient objects and its time dynamics.  ...  Given a 3D scene fused from the left-and right-views of a stereo video, 3D objects in the scene have two key attributes -shape and depth.  ...

Geometrically consistent stereo seam carving

Tali Basha, Yael Moses, Shai Avidan
2011 2011 International Conference on Computer Vision  
Naively retargeting each image independently will distort the geometric structure and make it impossible to perceive the 3D structure of the scene.  ...  Image retargeting algorithms attempt to adapt the image content to the screen without distorting the important objects in the scene. Existing methods address retargeting of a single image.  ...  This work was supported in part by an Israel Science Foundation grant 1556/10 and a grant from the Israeli Ministry of Science and Technology.  ...

Scene Carving: Scene Consistent Image Retargeting [chapter]

Alex Mansfield, Peter Gehler, Luc Van Gool, Carsten Rother
2010 Lecture Notes in Computer Science  
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 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.  ...  A retarget of the image is scene consistent if objects (1) are not distorted but kept as in the original image and (2) are placed in their correct depth ordering.  ...
