Improved Seam Carving for Video Retargeting

Abstract:
"Video, like images, should support content aware resizing. We present video retargeting using an improved seam carving operator. Instead of removing 1D seams from 2D images we remove 2D seam manifolds from 3D space-time volumes. To achieve this we replace the dynamic programming method of seam carving with graph cuts that are suitable for 3D volumes. In the new formulation, a seam is given by a minimal cut in the graph and we show how to construct a graph such that the resulting cut is a valid seam. That is, the cut is monotonic and connected. In addition, we present a novel energy criterion that improves the visual quality of the retargeted images and videos. The original seam carving operator is focused on removing seams with the least amount of energy, ignoring energy that is introduced into the images and video by applying the operator. To counter this, the new criterion is looking forward in time - removing seams that introduce the least amount of energy into the retargeted result. We show how to encode the improved criterion into graph cuts (for images and video) as well as dynamic programming (for images). We apply our technique to images and videos and present results of various applications."

Effective resizing of images should not only use geometric constraints, but consider the image content as well. A simple image operator called seam carving supports content-aware image resizing for both reduction and expansion. A seam is an optimal path of pixels on a single image from top to bottom, or left to right, where optimality is defined by an image energy function. By repeatedly carving out or inserting seams in one direction one can change the aspect ratio of an image. By applying these operators in both directions we can retarget the image to a new size. The selection and order of seams protect the content of the image, as defined by the energy function. Seam carving can also be used for image content enhancement and object removal. Various visual saliency measures for defining the energy of an image can be supported, and can also include user input to guide the process. By storing the order of seams in an image we create multi-size images, that are able to continuously change in real time to fit a given size.

Improved seam carving!

[PollenB]

*New* improved seam carving excuse me!!

[apocalypsynch]

Got me thinking. Thanks for posting this!

P.S. I hate when 'cubes' are drawn in the wrong perspective like that, even in furniture catalogs using whatever CAD program.

dvd is great for passing out copies but stinks for backup.

back up on hard disk - get a terabyte or greater internal SATA hard disk, get one of those usb connectors, keep the disk cool and back up on that.

[PollenB]

LOL. Ok! I'm sorta in limbo atm, that is until tomorrow morning, when I get my New Improved PC.

Duo Core Quad, 5mb ram yada yada. I've been busy dumping all my stuff onto DVD. Tiresome task.

I just get carried away!

Thanks for all your fine work. Wish you would do more on the subliminal faces.

[PollenB]

Much food for thought here Ozzy! Many thanks.

Thanks, but...

I have hundred of hours of media lies in high def mpeg2 to sift thru and document the TV fakery on!

When I'm done, if I am not blind...

[nanoprobe73]

lol i see orbs flying by my house

i have captured the little fuckers flying about!! very hard to see with the naked eye.

keep your eyes peeled to the skies

Wow! I see better and better moon shots!
