I have a photo of my friend, his ex-wife and a few others standing together on a camping trip. I wanted to share that photo with the group since it was the tenth anniversary of that trip, but didn't want to remind my friend of his divorce, so I used seam carving to elide his ex-wife. (The tool I used allows you to paint areas of low or high energy.) The result was almost seamless (pun intended) and you wouldn't notice anything amiss if you weren't looking for it.
