FROM VIDEO TO PHOTO
COMPUTER TECHNOLOGY
ORIGINATING TECHNOLOGY/ NASA CONTRIBUTION
Ever wonder whether a still shot from a home video
could serve as a “picture perfect” photograph
worthy of being framed and proudly displayed
on the mantle? Wonder no more.
A critical imaging code used to enhance video footage
taken from spaceborne imaging instruments is now
available within a portable photography tool capable
of producing an optimized, high-resolution image
from multiple video frames.
PARTNERSHIP
|
| Stored on a “distribution unit” the size of an index finger, Paparazzi™ software
generates clear, high-quality images from noisy,
grainy streaming video. |
RedHawk Vision, Inc. , a Costa Mesa, California-based
subsidiary of Irvine Sensors Corporation, developed
the “Real-Time Self-Contained Image-Motion Compensation
for Spaceborne Imaging Instruments” algorithm with
assistance from NASA’s Marshall Space Flight Center
under Phase I (1992) and Phase II (1998) Small
Business Innovation Research (SBIR) contracts.
By calculating the movement of a scene and then
repositioning it back to the original position,
the algorithm allows NASA to zoom and stabilize
video footage without loss of detail, extract photo-quality
still images, and even salvage dark, blurry, and
jumbled video that is otherwise unusable. RedHawk
Vision went on to complete another series of SBIR
contracts with the U.S. Air Force, further advancing
the video-to-photo software in preparation for
commercialization.
Released to the public in 2000, RedHawk Vision’s
Video Pics™ was the first product to evolve from
the NASA and U.S. Air Force collaborations. Video
Pics demonstrated the capability to successfully
extract 35-millimeter-quality photographs from
continuous video and produce digital files compatible
with image-editing software.
As the millennium progressed, so did digital technology,
prompting RedHawk Vision to create a new line of
video-to-photo software that could convert higher
frame-rate video into optimal image prints.
PRODUCT OUTCOME
|
| Paparazzi™ locks on the subject above and combines multiple frames to capture
video movement and excitement in precision
still images. Other sports enthusiasts, such
as the parachuter below, use the video-to-photo
software to capture exciting action images. |

The new Paparazzi™ stand-alone video-to-photo processing
software generates clear, high-quality images (300
dots per inch) from noisy, grainy streaming video,
much in the same way that the human brain “sees”
video content: scene by scene. Paparazzi takes
the best parts of multiple frames of video and
overlays them to create an image of superior quality
in less than 10 seconds, unlike a frame-grabber,
which extracts images from only a single video
frame and at a much slower rate. As a result, Paparazzi
catches extra details unattainable when using a
frame-grabber, such as the exact time displayed
on a wristwatch being worn by an individual in
motion in a video.
In addition to combining video frames, Paparazzi
adjusts pixel aspect ratio and corrects color.
Controls for brightness, contrast, saturation,
and hue let users fine-tune lighting as they would
with any type of photo-editing software. Other
features include zooming and cropping, optimized
black & white processing, noise reduction, and 16:9 video support (16:9 is considered
the new “standard” for digital television broadcasts).
The Paparazzi software and its supporting files
are supplied on a Universal Serial Bus (USB) Flash
drive “distribution unit” the size of an index
finger, allowing for quick and easy transport of
print-ready images between computer systems. To
access the software, the user simply plugs the
distribution unit into a computer’s powered USB
port and double-clicks on the associated icon in
the drive’s window. Paparazzi processes all video
files that play on personal computers via the Apple
QuickTime® downloadable media player.
In 2003, Paparazzi saved the day in a “one off”
situation where a wedding photographer failed to
make it to the church for a wedding ceremony. Brian
Coe, the owner of an events videography firm just
outside of Paris, France, named SQYnet Productions,
purchased the video-to-photo software in order
to supply stills to a “tearful bride” who inquired
whether photos could be extracted from her wedding
video. With Paparazzi, Coe was able to extract
40 high-quality photos from the video to satisfy
the customer’s request. SQYnet Productions has
since incorporated Paparazzi images as an option
for some of its standard wedding packages, leading
to increased revenues for the company. With Paparazzi
retailing at $279, Coe is happy to report that
the software technology has already paid for itself.
Other applications for the technology include forensics,
where crime investigators can use the software
to decipher clues potentially caught on nighttime
surveillance tapes, as well as astronomy, where
astronomers can obtain sharp, distortion-free images
with a combination of video recorder and a telescope.
