Two scientists at NASA Marshall Space Flight Center, atmospheric scientist Paul Meyer (left) and solar physicist Dr. David Hathaway, have developed promising new software, called Video Image Stabilization and Registration (VISAR), that may help law enforcement agencies to catch criminals by improving the quality of video recorded at crime scenes, VISAR stabilizes camera motion in the horizontal and vertical as well as rotation and zoom effects; produces clearer images of moving objects; smoothes jagged edges; enhances still images; and reduces video noise of snow. VISAR could also have applications in medical and meteorological imaging. It could steady images of Ultrasounds which are infamous for their grainy, blurred quality. It would be especially useful for tornadoes, tracking whirling objects and helping to determine the tornado's wind speed. This image shows two scientists reviewing an enhanced video image of a license plate taken from a moving automobile.

Two scientists at NASA's Marshall Space Flight Center,atmospheric scientist Paul Meyer and solar physicist Dr. David Hathaway, developed promising new software, called Video Image Stabilization and Registration (VISAR). VISAR may help law enforcement agencies catch criminals by improving the quality of video recorded at crime scenes. In this photograph, the single frame at left, taken at night, was brightened in order to enhance details and reduce noise or snow. To further overcome the video defects in one frame, Law enforcement officials can use VISAR software to add information from multiple frames to reveal a person. Images from less than a second of videotape were added together to create the clarified image at right. VISAR stabilizes camera motion in the horizontal and vertical as well as rotation and zoom effects producing clearer images of moving objects, smoothes jagged edges, enhances still images, and reduces video noise or snow. VISAR could also have applications in medical and meteorological imaging. It could steady images of ultrasounds, which are infamous for their grainy, blurred quality. The software can be used for defense application by improving recornaissance video imagery made by military vehicles, aircraft, and ships traveling in harsh, rugged environments.

Seen here in March 2023, prototype hardware for the Venus Interferometric Synthetic Aperture Radar (VISAR) underwent interface testing at NASA's Jet Propulsion Laboratory in Southern California. VISAR is being developed at JPL for NASA's Venus Emissivity Radio Science, InSAR, Topography & Spectroscopy (VERITAS) mission that will launch within a decade to explore Earth's twin. These early interface tests are the first in a series to be run by JPL and Thales Alenia Space Italy (TASI), an international partner of the VERITAS mission that is contributing hardware to the instrument.  Figure A shows TASI engineers Luca Di Marco Napini and Gabriel Mihu working in a JPL cleanroom on the VISAR prototype hardware.  When VERITAS arrives in orbit, it will use VISAR to create detailed 3D global maps of Venus. The spacecraft will also carry a near-infrared spectrometer to figure out what the surface is made of. Together, the instruments will offer clues about the planet's past and present geologic processes, help reveal how the paths of Venus and Earth diverged, and how Venus lost its potential as a habitable world. VERITAS is managed by JPL.  VERITAS and NASA's Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission were selected in 2021 under NASA's Discovery Program as the agency's next missions to Venus. The Discovery Program is managed by the Planetary Missions Program Office at NASA's Marshall Space Flight Center in Huntsville, Alabama, for the Planetary Science Division of NASA's Science Mission Directorate in Washington.  https://photojournal.jpl.nasa.gov/catalog/PIA25832
First Tests for the VERITAS' Venus Interferometric Synthetic Aperture Radar
Seen here are members of the international team that participated in recent tests on prototype hardware for the Venus Interferometric Synthetic Aperture Radar (VISAR) at NASA's Jet Propulsion Laboratory in Southern California. VISAR is being developed at JPL for NASA's Venus Emissivity Radio Science, InSAR, Topography & Spectroscopy (VERITAS) mission that will launch within a decade to explore Earth's twin.  In March 2023, the hardware underwent early interface tests in a JPL clean room, representing the first in a series to be run by JPL and Thales Alenia Space Italy (TASI), an international partner of the VERITAS mission that is contributing hardware to the instrument. Dressed in gowns to minimize the risk of contamination with sensitive electronics, the JPL VISAR digital team and TASI engineers pose for a photograph next to the laboratory benches where the tests took place.  Figure A shows the same personnel without gowns for a team photo. From left to right: Marvin Cruz (JPL), Chester Lim (JPL), Tim Noh (JPL), Hana Haideri (JPL), Luca Di Marco Napini (TASI), Ernie Chuang (JPL), Dragana Perkovic-Martin (JPL), and Gabriel Mihu (TASI). JPL's Michael Burke, Anusha Yarlagadda, Duane Clark, and TASI's Antonio Delfino also participated in the tests but are not pictured.
