"Content-Aware" Smart Image Resizing Algo

Alex

Everyone who has ever worked with digital images know that you resize an image either by cropping it (and potentially lose important parts of the image) or shrinking it (and lose size or contend with a distorted image).

Ariel Shamir of the Efi Arazi School of Computer Science in Herzliya, Israel, shows us another way: content-aware "smart" image sizing, where you can have your "image cake" and eat it too (you'll see what I mean):

Retargeting is a new technology focused on solving problems with changing sizesof digital photography, while traditional crops often fails to include all elements and resize may make the image too small to distinguish, retargeting, using an algorithm, recognizes what's relevant to the image, and column by column of pixels are removed.

Check out rsizr.com for a free Flash-based implementation of seam carving that lets you resize your own images, both in height and width simultaneously, in real time. (You can rescale and crop images too!)

Hi,
If you are looking for a software to try out seam carving, take a look at www.thegedanken.com/retarget

The program that you can download there (for Windows and Linux, and free) is already highly optimized concerning speed, and apart from enlarging or decreasing image size you can also use masks to protect or delete certain parts of your image.

Have fun,
Irmgard

As a mom, all I can say is that I wish there was a website of all these videos of people being stupid. It could be called, "No, Don't Do That!" Kids could watch it everyday to learn why they shouldn't do things like play hockey with a burning puck after dousing their hockey gear with lighter fluid. Or skateboard without protective gear. Or hang their bodies out of car windows while attempting to steer with their feet. Or jump off the roof into a pile of ANYTHING. Or try to use their rectum as a bottle-rocket-launcher.

Or try to pull down a tree that is longer than their truck with said truck.

It would save parents a lot of lecturing which kids don't listen to anyway.

So there was a guy driving the truck, right? WTF? Those losers stand around like nothing happened. Wasn't the guy crushed?

Aside from that, this is another good reason to encourage math studies in school, especially geometry.

I wish I could say "What unique idiots" but I can't since I have a history that is far worse, trying to lower a tall (100'?) transmitter tower using only a military 6X6 on a windy ridge.

Good news is it didn't hit any body or any thing of value.

100' an exaggeration? Truth is I have no idea anymore, but there were three or four guy wires at each anchor, and when we hack-sawed up the thing the pieces filled the 6X6.

And actually, the driver exits the driver's side door.

What did I expect to see? Either that, or the broken cable knocking the house down (I assume it wouldn't have been shown here if the broken cable had beheaded somebody--which is a high likelihood outcome--consider if the cable had broken near the tree. The real idiots are the people standing around, the driver is relatively safe inside the truck.

Before the palmetto hit the truck, I was thinking, "that can't be good for the clutch."

You know, I don't think I've ever seen a palm tree up close. My travels throughout this grand country have neatly circumvented the areas in which palm trees are common. There are a lot of monkey puzzle trees around here, though.

thank you for a good laugh! they are really lucky the wire didn't snap first and take one of the morons standing next to the truck out. and how could they not even flinch or visibly react to a tree falling onto a truck??

That's just like those Funniest Videos shows. I hate that I love them, but I love them. Everytime they open a shot on a trampoline you just know it's going to be gold. When will we learn that gravity is NOT our friend.
