Improved seam carving for video retargeting

Michael Rubinstein, Ariel Shamir, Shai Avidan
2008 ACM SIGGRAPH 2008 papers on - SIGGRAPH '08  
Video, like images, should support content aware resizing. We present video retargeting using an improved seam carving operator.  ...  The manifolds are found using a new forward-energy criterion that reduces both spatial and temporal artifacts considerably.  ...  We would like to thank Matthew Brand for his comment on energy inserted to the image during the retargeting process, that led to the formulation of forward energy.  ...

Seam carving for stereoscopic video

Benjamin Guthier, Johannes Kiess, Stephan Kopf, Wolfgang Effelsberg
2013 IVMSP 2013  
In this paper, we present a novel technique for seam carving of stereoscopic video. It removes seams of pixels in areas that are most likely not noticed by the viewer.  ...  When removing seams in two consecutive frames, temporal consistency between the removed seams must be established to avoid flicker in the resulting video.  ...  Rubinstein et al. extended the seam carving approach to the resizing of video [5] . They represent a video as a 3D spatial/time video cube. Graph cuts are used to find minimal energy seams.  ...

Discontinuous seam-carving for video retargeting

Matthias Grundmann, Vivek Kwatra, Mei Han, Irfan Essa
2010 2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition  
We introduce a new algorithm for video retargeting that uses discontinuous seam-carving in both space and time for resizing videos.  ...  Our algorithm relies on a novel appearance-based temporal coherence formulation that allows for frame-by-frame processing and results in temporally discontinuous seams, as opposed to geometrically smooth  ...  This improves upon the forward energy measure of [13] . We demonstrate the effectiveness of this formulation on image resizing applications as well.  ...
