A new software program called VISAR is helping Dr. Stephen Planck, an associate professor for the Casey Eye Institute at the Oregon Health Sciences University in Portland, study immune system diseases. "The eye is a good organ to study because it has a window," says Planck. "We track cell movement over time, which helps us understand how the body responds to disease. We can answer questions that advance our understanding of processes unique to the eye and our understanding of how the immune system works," says Planck. "We could see cell movements inside the eye that were undetectable before."
VISAR, which stands for Video Image Stabilization And Resolution, was developed at NASA's Marshall Space Flight Center (Huntsville, AL) by Dr. David Hathaway and Paul Meyer for turning into clear stable images the dark jittery video images of violent explosions on the Sun. Now the technology is being transferred to other applications.
The new software corrects for horizontal and vertical motion, which is unlike other software that only removes "snow" from videotape. VISAR also corrects for rotation and zoom effects.
NASA is currently inviting companies to submit license applications and commercialization plans. For more information, call (256) 544-0034 or (256) 544-6540. Written inquiries can be submitted to Marshall Space Flight Center, CD 70, Huntsville, AL 35812 or www.nasasolutions.com.
