SP -- VISAR INDUSTRY BRIEFING -- NASA'S VISAR VIDEO STABILIZATION OFFERED FOR LICENSING NASA's VISAR Video Stabilization Offered for Licensing NASA's Marshall Space Flight Center (MSFC) is offering its state-of-the-art process for video image enhancement to U.S. companies for licensing. An industry briefing on Video Image Stabilization and Registration (VISAR) will be held Wednesday March 24, 1999 at MSFC in Huntsville, Alabama. At the request of federal law enforcement officials, MSFC developed VISAR for use in investigating a nationally famous crime. Home video footage taken at the scene was blurred and unclear. Processing with VISAR produced impressive results, and subsequent reviews by Los Alamos National Laboratory concluded that VISAR was unsurpassed in its clarification of distorted video images. In the past, video stabilization has been limited to registering horizontal and vertical image movements. These methods do not account for rotational or zooming effects in video data sequences, and are sensitive to the effects of parallax when items in the background and foreground move atdifferent rates and/or different directions. VISAR can correct images when of all of these adverse effects are present. VISAR also eliminates other video flaws. Jagged edges found in still images extracted from video can be smoothed, and 'snow' caused by video noise is reduced by adding several registered images together. Deblurring techniques offer additional improvements. A Windows-based version of VISAR is currently being used as a video post-processing tool. The methods, however, are not limited to software. With electronic hardware support, the speed of VISAR can be enhanced, making real-time video stabilization for many custom applications possible. The briefing will demonstrate the technology, allow companies to ask questions of the VISAR inventors, and offer instructions for licensing technology from NASA. One-on-one consultation sessions will also be available. VISAR Industry Briefing -- Wednesday, March 24, 1999, Marshall Space Flight Center, Huntsville, Alabama.
