Discontinuous Seam Carving for Video Retargeting

[grumbel45]

Wouldn't it be possible to combine seam carving of vertical lines with the insertion of horizontal lines? Thus requiring less horizontal squish on the image while still filling a 4:3 aspect ratio. Anybody tried that?

UltraNice technology! Youtube MUST use it

It is not reversible, but you can re-expand images using seam insertion and they end up pretty close - generally better than squash & stretch ;-)

Pretty technique :-D

It this going to happen in real time? If so, won't you need a powerfull GPU and/or CPU.

Other than that it seems like it is working really well.

@sjark5000 depends how efficient the software is.

Very interesting and very clever.

I would like to point out a specific problem related to these tecniques: they are not invertible (if you only have the retargeted video you can't reconstruct the original) and they may therefore lead (in the case you are only left with the retargeted video) to the loss of the original video.
