PhotoSketch Image Manipulation Tool Taking the World by Storm
PhotoSketch, a new image manipulation program that combines stick-figure sketches, internet image search and pattern matching, seems to be spreading like wildfire. Created by five Chinese students at Tsinghua University and the National University of Singapore, the tool takes a basic sketch and simple labels and turns it into a polished image. "Although online image search generates many inappropriate results, our system is able to automatically select suitable photographs to generate a high quality composition, using a filtering scheme to exclude undesirable images," say the PhotoSketch team in an abstract outlining the tool. "We also provide a novel image blending algorithm to allow seamless image composition. Each blending result is given a numeric score, allowing us to find an optimal combination of discovered images. Experimental results show the method is very successful."

And the binaries (it's a few command line programs, so no fancy UI)
This image looks sketched. I can tell from a few of the pixels, and from having seen a few sketches in my time.
If you sketch a big circle and two hands, will it come up with goatse?
The authors of the program--Tao Chen, Ming-Ming Cheng, Ping Tan, Ariel Shamir, and Shi-Min Hu at the Department of Computer Science and Technology, Tsinghua University, and the National University of Singapore--presented it at Siggraph Asia 2009.

Now NO ONE will believe the pics of me with Jessica Biel, Kate Beckinsale and Dolly Madison are real!

I tried to draw a picture of a man with an erection. I labeled him "porn guy". Then I drew a picture of a woman with her mouth open and labeled her "porn whore cumshot".
The composite picture was fine except that the man and the woman were far apart from each other. In addition, even if I were to draw them closer together (hey, I'm working with a mouse here), the result would still have been sized incorrectly.
This technology holds lots of promise and is already pretty cool. I hope they can work out the kinks.
The reality is that it was only a matter of time before someone came up with something like this, with examples like Microsoft Photosynth, but this is an unbelievable implementation.
I'm not 100% sure, but I can definitely see the potential for Google to snatch this up really fast and incorporate it into Picasa or even google image search or something. The fact that something like this allows anyone (not just artists) to come up with novel images with minimal effort is fantastic. I do wonder how canned the images were though. IE: did they GIS for an image first, then use the image as a basis to draw the stick figure, knowing that their algorithm would pick the image they selected in the first place? I would like to see a live demo with an unplanned audience member doing the drawing. Then I'll really be impressed.

It says in the Vimeo link. Not gonna summarize it cause just look at the damn thing
Soon I can write a story and then I just compile it and it will show sniplets of existing movies or rendered characters and woha it's converted to a real movie even with end credits: Directed and written by ME ME
Oh I can't wait.
It appears from the video that it's running a fairly sophisticated series of algorithms to compare backgrounds and determine how difficult it would be to do a convincing mask-out of the foreground object, of which it appears to have a sort of heuristic expectation of shape from the user's sketch.
For instance, if your background is a grassy field, the user has requested a dog running, and you have a photo of a dog running over grass and a dog running over pavement, the grass one will allow a greater margin of error in the masking and thus it gets selected.
Overall, this looks like a fantastic step forward for computer vision, bringing the computer ever closer to the non-Cartesian way our brains see.

That's pretty damn cool. It reminds me of scene completion, which is another take on the same idea - combining images from Flickr to create new images according to a brief sketch.
Having just taken a quick look through the config files and readme from the binary.zip file, it's pretty obvious this is very much a Proof of Concept release. You need to hard-code the number of sketched items, label them each in the config file, download the potential matched images to a specified directory, etc. It involves enough guess-work and too little documentation for me to proceed further, which is unfortunate. Has anyone else actually gotten it to work as described to confirm it does what it claims it can?
Anybody else see what's wrong with this picture?

1) Open Source?
2) Could the algorithm be used to find existing images similar to the one you just drew?
3) When is a demo of this thing available?

This seems to be either a hoax or will be extremely limited in ways they aren't discussing, as to have little use. If the examples they are showing are real, the image data set they are pulling from must have been manually processed and adorned with hand-made metadata.
This falls too much into the "too good to be true" category for me to believe it.
An interesting point: This research is being done in China, not the United States. Whatever happened to basic research being done in the US? Today's PARC laboratory is not in the US, but appears is in China.
This is not a good thing for people who live in the US. America's increasing dependence on outsourcing is destroying the US' capability to be competitive in today's environment.
The Harvard Business Review has an excellent article about how America is destorying its own future.

No. Mashups are clearly derived works, which fall under copyright quite clearly. Since this is in China, I'm pretty they're ignoring an IP laws and will probably get away with it. In the U.S., however, every one of those images better be licensed for royalty-free distribution, or they'd be sued.

Wow. I'm instantly instilled with the urge to plug an XKCD comic into this and see what happens.
I suppose it won't work if you try sketching the Dalai Lama?
I've heard of academic projects on filtering out porn (Australian military didn't want people surfing smut on the clock). I'd imagine that filtering out pics of the Dalai Lama would be harder...
Someone should take all the XKCD comics, mark 'em up a bit, turn 'em into nice pictures, and .... Profit!!

You know your old when you don't regonize any of the names of today's hotties. And think they should cover up their bellies, do they want to catch a cold?
Good job slashdot btw, on holding out the sex comment so long.
Me, I thought of the porn possibilites when I read the first line.

The fact that a Chinese university is doing cutting-edge research is a good thing for you Americans. That means they're getting richer, thus a growing market for the pop culture products and Hollywood entertainment you're so good at exporting. Maybe 80% of the entertainment in the telly here in Denmark (in Europe) is from the US.
Now you just need to teach them to abide your copyrights. Maybe they can teach you how to eat vegetables in return. Fix an obesity problem or two, eh?
Isn't this the visual equivalent of a mashup?
Aren't mashups already in a copyright gray area?
In the US we have this really fucked up way of dealing with derivative works - the more complicated the work, the less of it needs to be incorporated into another work before it is considered an infringement. Yes, that's right the more information in the original the smaller the percentage of that information is required to disqualify any fair use defense.
So you can quote a couple of lines of a short poem in a book or even have a character speak them in a movie and that's generally OK. But sample just 3 notes of another song and you are in deep doodoo. Similarly, any background artwork in a movie - simply just pictures hanging on the wall in the background of a scene and thus mostly out of focus and of very low effective resolution require clearance and licensing fees, frequently absurdly high fees and of course just about any clip of video used in another movie or show - even on a television in the background of a scene - is going to require licensing too.
Most hollywood studies have an entire division devoted just handling these clearances (look in the credits for most movies and you'll see at least one person credited as head of the clearances group). This practice has the effect of keeping the "little guys" out of the motion picture business similar to the way patent pools are used to squash tech start-ups - all the studios have large "pools" of our culture under their copyright and the independent artist can't afford to license any of it for his work while the other studios can make each other sweetheart deals that guarantee cheap and easy access to each studio's "pool" of culture.
So no, mash-ups, since they generally are 100% composed of samples of other songs, aren't anywhere near being gray in the USA.
When information is power, privacy is freedom.
Aren't mashups already in a gray area?
The problem is that you're letting your potatoes get exposed to air for too long before mashing them. Submerge them in iced water prior to mashing, and add some sour cream to the mash, then your mashup will have a creamy texture and clean white color.
... and then they built the supercollider.
