nsf.gov — The FBI has a storage problem. They've got 50,000,000 sets of fingerprints to store, and they're adding 5,000 a day. With that large a population, even very small file sizes add up. So researchers at the University of Texas at Austin used a evolutionary algorithm to create a better image compression format. Compressed fingerprint image quality increases after generations of genetic algorithm compression!

"ok so taht means i can store 5 times as much porn on my computer now? sweet."Only if you have a finger fetish ;)(yes I know how stupid that is but I couldn't resist)

50,000,000? Are there really that many criminals in the world? Maybe they should start deleting some of the ones whose owners have died already.

"...and they're adding 5,000 a day. I find that disturbing."Actually, that breaks down to 100 people per state per day. That's not that many when you think about it. You would be surprised to know what will get you in that database. A couple of years ago my wife and I went through a state sponsored foster parenting program. During the background checking process, they fingerprinted us. In reading the fine print, I saw that our prints would be sent to the FBI and retained. So even though neither of us have ever been in trouble with the law (well, I have one speeding ticket) - both of us have prints on file in that database.

The 50 million isn't just criminals. The armed forces, government workers, law enforcement, teachers, banks, and other areas take fingerprints also.

Fingerprint images are larger than 2bits. Minutiae for two fingerprints is 200bytes. A full tenprint record, with WSQ compression of each fingerprint image, is about 750Kbytes.

I, for one, welcome our new American overlords.

doesn't your everyday avid porn collector run into this problem after about a month of getting broadband? maybe they should survey porn sites...

Jpeg2000 is a wonderful format, yes it is a standard, and some of you *cough*mediaphile*cough* need to brush up a little on your jpeg2000 info. Licensing has also changed on some open source jpeg2000 decoders so there is really no reason it is not in browsers today. I guess the state of browser incompatibility is a product of the misinformed.

"So when is the everyday browser going to support this nifty new image compression? Bandwidth is kind of costly these days."so then use bittorrent or 7z all your files or make a browser that will open up 7z files and open a html file inside and revolutionize the web : )
