quality and everyone has seen a movie with a scene where a lab
technician solves the case by cleaning up the poor quality video from
a security camera. MotionDSP, a company that is partly owned by
graphics chip designer Nvidia Corp., claims that its vReveal software
can enable never-before-seen video enhancements.
vReveal features patented super-resolution technology adapted from the
forensic applications used by law enforcement and intelligence
agencies. With vReveal, consumers can dramatically improve the quality
of videos captured by cell phones, digital cameras and other handheld
devices. It uses familiar one-click touch-up tools to stabilize,
brighten and sharpen flawed videos.
MotionDSP's vReveal can run on any system with Windows and a 1.6GHz
microprocessor (preferably dual-core) or faster, but with Nvidia
GeForce 8-series and later hardware it can work about five times
faster, according to the software company.
Theoretically, such super-resolution technology can be applied in
real-time to enhance DVD and make them look considerably better on
high-resolution monitors. However, at this time MotionDSP only offers
its technology as part of its vReveal aimed at consumers as well as
Ikena, which is aimed at professional investigators.
MotionDSP's technology extracts information from multiple frames of
video, reconstructing details not visible in the original sequence.
Ikena can then output both enhanced video sequences and
high-resolution stills. Unlike standard frame-averaging techniques,
Ikena's algorithms are capable of tracking complex motion, and can
therefore enhance both moving and non-moving objects, and complex
scenes which combine both camera motion and object motion. Ikena's
multi-frame algorithms can significantly reduce both sensor and
compression noise.
