"We can see that the area with the least visual information (the sky) has been reduced while other regions of the image such as the boat, water, and buildings, remain intact." Except the tower on the right has been "redesigned" by the algorithm.

... It's a feature! Algorithms with input on design are the new hotness.

Well, I can't get to the site now, but I've seen seam carving before. What's impressive about seam carving is the bang-for-the-buck... it's a rather simple algorithm that has quite spectacular results. But it's certainly not perfect. When you're taking an image like that and throwing away information, there isn't a definition of "perfect" anyhow. Information is being discarded, so, information will be lost. The question is what distortion the image will have, not whether the image is distorted.

The castle looks exactly the same... what was "redesigned" ?

  You don't notice the difference between the proportions and distance between the woman/sky and the castle? The clouds are much smaller/thinner and the woman is a fraction of the distance apart. (Edit: Nevermind, I mistakenly thought you were trying to say you didn't see a difference. Not that you were countering their point that the castle was "redesigned".)

    That is what seam carving does. What do you think was supposed to happen? Look at the pics again, the castle is exactly the same. The grass, sky and distance between person has been changed. The whole point is to shrink the dimensions by keeping the main things as they are in size, detail and proportion and cutting out the stuff in the middle.

      No kidding. In the comment I was replying to you said you didn't see a difference. (Nevermind, I misunderstood your comment.)
