Content Aware Image Resizing.

[lkroll]

Also known as Liquid Resize. Thought I would share you this site where you can download a standalone that currently implements part of this cool implementation of Dr. Ariel Shamir's algorithm that most, if not all, of you saw on YouTube (sorry; YouTube link wasn't working, so I had to link DPR's link of the video). Can also follow this blog for some others who are following this cool technology.

As an FYI this guy is now working at Adobe so we should see some cool stuff coming out of this.

this is awesome stuff I saw it a few weeks ago, very impressive and the removal side of things will be invaluable alone.

The latest version at thegedanken.com has implemented the erase with brush feature, but I haven't tried this yet (horse power issues with my aging PC). I have played with the program on a few images and am quite pleased with the results (but not the processing time; lol). They still haven't implemented the uprezing yet, but they are working on it.

I like it, the delete needs some kind of feather to help heal better but the protect works very well, combinded with some retouch in PS you can get some very cool results. I am suprised to see something like this come out for free use.

Am attaching a before and after shot done with this software.

Note what has happened to the speed limit sign in the reduced one.

Since this is a first try with this, is there a way to avoid this?

As Creeduk found, you can use the protect brush on the pole too. May also want to protect the vehicles too since they look like they've been munchkined. lol

I tried the protect brush and found that it works on some images. Didn't seem to work here.

Also the You Tube video is nice, but nowhere does it show a screenshot of the work area. Where can I find explanations for the controls and when to use what. I have groped a bit and come up with a few things on my own, but a "getting started" type intro to this would really help. The PDF instructions go into a lot of algebraic formula and that ain't in my field of expertise.

You first have to understand the Dr. Shamir uses a custom program (i.e., not the same as the one from thegedanken folks (they developed their program based on Dr. Shamirs specs). Also thegedanken program hasn't implemented the uprezzing feature yet (though I believe they are working on it). Still, I'm quite impressed with what they came up with. I just wish that Dr. Shamir would opensource his program since he publically (and it's under university research) showed it at SIGGRAPH. Oh well.

OK, that certainly clears up a few things.

I shall now continue with my "Bible method", (seek & ye shall find), to try a few more things.

BTW, found that you can get some rather interesting looking people by playing with the protect brush. (See attached). Haven't found a way as yet to come close to the examples as far as simply resizing is concerned. Guess that will come as I play with it more. Still a lot of distortion even after using the protect brush when resizing.

Suggestions always welcome.

Now that's just too cool Steve. Really made me almost fall out of my chair.

Very important link. Looks like they finally ported the compiled executables (found the update from the GIMP Registry) for the GIMP.

Hey! I may make more use out of it this way than by using it to resize. (More fun anyway.)

It has some fun results that is for sure. With careful protect and delete I have had some success (just for test) removing text added to images but keeping other content.

The example
i tried was a woman running on a beach, the text was running along the bottom but about 25 px inset from the bottom edge. I selected the text as delete area and the woman as protect and added about 80-85% scale, she was maintained along with the reflection in the water (wet sand) and the text was removed.

Has promise that is for sure. I emailed the addy and suggested a soft edge brush if possible to help blend the scaling.

Excellent idea.......gonna have to try that.

Just want to keep this thread updated. Currently, I now use a GIMP plugin to do these (like the control). Still, I have to share with you all a link that I received from Photojojo (newsletter that I subscribe to). It's an online only solution to this; realtime animation is cool too.
