File Information
Description	illustrative example of Seam carving for content aware image resizing usage: carvedimg=seamcarving(im,k) k is how many vertical seams to remove. im is the image. example: img=imread('peppers.png') carvedimg=seamcarving(img,50) image([carvedimg img]); axis equal; Author: Aslak Grinsted 2007... Based on ideas from Avidan & Shamir: http://video.google.com/videoplay?docid=-6221880321193117495 Note i haven't read their paper and they have probably lots of smart tricks for optimizations.
Acknowledgements	This submission has inspired the following: Seam Carving for content aware image resizing: GUI implementation demo
MATLAB release	MATLAB 7 (R14)

04 Sep 2007	Gerd Kunert	Requires Image Processing Toolbox!
05 Sep 2007	Aslak Grinsted	It only requires image processing toolbox in order to load the demo images. Try loading one of your own and applying it to that instead. --Anyway i have tried to remove this dependency in a new version just uploaded.

Updates
29 Aug 2007	Improved various small things suggested by Doug Hall and made some small optimizations. * handle grayscale images * add nice demo mode
29 Aug 2007	Fixed a bug that prevented it to run outside demo-mode.
29 Aug 2007	Changed costfunction to the same as used in the google video clip. works better for some images but slightly slower.
27 Sep 2007	* Removed demo dependency on the image processing toolbox. * Made compatible with older versions of matlab.
