Well, demand has been pretty steady for the Seam Carving GUI so I've gone ahead and updated it to the latest version of CAIR. Joe says there should be some model performance improvements and possibly some behavior fixes.
Last week a link to the Google Code page for the application made it pretty high (6th or 7th) on programming.reddit.com which brought in a flurry of traffic :) I hope some people found the program useful.
I have relicensed the program as GPL v2.0 and Joe will be relicensing CAIR as LGPL v2.1 (and gave me permission to redistribute it under that license). This came after a commenter notified us of the incompatibility of GPL v3.0 and Qt4 from Trolltech which is GPL v2.0. Apparently v2 and v3 are incompatible licenses. I find in unfortunate that an open source license is creating these types of divisions and inconveniences in the free software community, but the folks in the GPL v3 camp are vary passionate about the IP stuff that the v3 license protects even to the detriment of license compatibility.
As usual, get the latest source and binaries at the seam-carving-gui download page.
