Video Image Stabilization and Registration (VISAR) Two NASA researchers — using their expertise and equipment for analyzing atmospheric satellite video — created technology that can dramatically improve video images, including crime scene videos. Working with law enforcement, the scientists began to use their computer software to turn poor images captured by home video, security systems, and video cameras in police cars into clearer, stable images that revealed clues about crimes. The scientists' invention — called Video Image Stabilization and Registration, or VISAR — stabilizes camera motion in the horizontal and vertical, produces clearer images of moving objects, smoothes jagged edges, enhances still images, and reduces "snow". |
| About Intergraph Government Solutions For 8 years, VISAR was licensed to Intergraph Government Solutions and incorporated into a video tracking and enhancement system developed by the company. Intergraph's VideoAnalyst™ became a comprehensive, effective, and affordable solution for advanced video analysis and enhancement, combining capabilities previously found only in high-end broadcast-quality systems with the tools necessary to capture, analyze, enhance, and edit almost any type of video. |

| Looking Ahead
VISAR holds tremendous promise in a variety of other applications as well. Military uses include intelligence, surveillance, and reconnaissance. A host of medical applications include the clarification and stabilization of grainy ultrasound images, clarification of cell images viewed through a microscope, and retinal study stabilization of eye images. |

| Infusion
NASA's Marshall Space Flight Center and Kennedy Space Center have both utilized VISAR, and so have other federal agencies, including the FBI. VISAR has been used successfully in a criminal case for the NASA Inspector General involving foreign nationals, and it has also been used to analyze various Shuttle launches and footage of the Space Shuttle Columbia. |
