Rsizr - Seam carving & content aware image resizing - AWESOME!

Hey guys,

This is some truly awesome stuff in the scene of image processing.
Re-inventing the wheel in a way.


First, watch this slightly boring video to understand it :




Next, visit this tool that has been built in flash that actually lets you seam-carve your own images!!

rsizr - intelligent image resizing

Instructions:
1. Upload an image (the smaller the image the faster it'll be [try in the range of 640x480 to 800x600]
2. Use the slider on the left and the slider on the top to specify how many seams you want the software to find (do about 50% of your image or more)
3. If its taking too long you can slide the slider back into the blue area to stop it.
4. After it is done finding the seams, you can use the handles to resize the image in a content aware way and see how cool it is!

5. You can use the "preserve" and "remove" brushed to select parts of the image you wish to keep or get rid of. This helps when the automatic setting is chopping up valuable stuff in your images.
6. This isnt magic, so choose an image which has a main subject and a fairly generic background.

Here are two really quick examples i did.

The first one using "remove", the second set using "preserve".






The first image is from our Jirad drive (see the thread here)

The second is some rubbish picture i found on the internet somewhere. lol

Awesome stuff Rehaan, but look at the first pic; It didnt remove the shadows, guess the shadows have to be handled in PS.

Hey hellwrath & thefreak,

As i said earlier, this isnt magic, so i had to be realistic with the area i chose to remove. (It gets a little tricky when there is something that is a continuous line and not perfectly horizontal in the background.

Its amazing because this is a more "organic" way of resizing pictures as opposed to stretching/quishing straight rows and columns of pixels.

Check out some more samples here : rsizr lets you intelligently resize your images — gallery

ps - Did you guys try it or no??

The shadows look like ghosts on the beach.

Yes, it will be fairly processor intensive (especially since this is being done through a tool thats a flash website)

I guess that after you have loaded the site, you can be offline and it still should work.

Also, i have heard of photoshop plugins like this, but have never tried em.

-- 2 years later --

If you have firefox 3.5 or higher, the browser can now handle seam carving in JavaScript!

Demo : Content Aware Image Resizing implemented with JavaScript

Thanks Sammyboy.

Heres some more cool imaging stuff -- a preview on possible additions to Photoshop CS5 (along similar lines as the above stuff).

I think CS4 has already got it, although you got to pay up 40k+ for it.
