  • Computer screen showing the closeup of a human eye with crosshairs over the pupil. Caption: and nearly impossible to fool or spoof.

    While many of rely on passwords to protect their identity, there's more sophisticated identity recognition technology called "biometrics" for use. Security measures that use biometrics rely on a person's unique characteristics and traits rather than on what that person can remember, such as a password. Ocular biometrics, in particular, relies on iris and retinal scanning. With support from the National Science Foundation, computer scientist Oleg Komogortsev and a team at Texas State University are taking the technology a step further, making it even more secure, reliable and nearly impossible to fool. Part of the National Science Foundation Series “Science Nation.”

  • Two people sitting at computer screens while a person on stage plays a wind instrument. Caption: to teach the computer to play the clarinet too.

    University of Rochester electrical engineer Mark Bocko has combined his passion for music with his passion for engineering, devising a way to digitally compress music files. Bocko’s team of engineers and musicians at Rochester’s Eastman School of Music are also helping uncover some extraordinarily precise details about just how music is made. With support from the National Science Foundation, they have built a computer model of the clarinet, entirely from real world acoustical measurements taken from human musicians. Measuring such things as how hard the musician is blowing into the instrument and the pressure the musician applies to the reed, they have modeled the way music is made.

  • Wire frame diagram of a round building with columns and arches. Caption: They're rebuilding Rome pixel by pixel

    The ancient city of Rome wasn't built in a day, but now that city, along with all its famous landmarks, can be digitized in just a matter of hours. A new computer program under development at the University of Washington in Seattle combs through hundreds of thousands of tourist photos on Flickr and other photo sharing sites and reconstructs the city – pixel by pixel. Now, viewers can fly around many of Rome's famous landmarks on their computer in far more detail than they'd ever be able to on current virtual map programs such as Google Earth. The new technique may one day create online maps that offer viewers a virtual-reality experience. The software could build cities for video games automatically, instead of doing so by hand.
