Real-time video stabilization of PAL or NTSC video images. Improves the operational performance of high-zoom surveillance cameras. Operates with live or recorded video. Compact, simple to install hardware. Can improve the performance of compressed video links. Applications: > Town centre CCTV > Cross-border monitoring > Long-range covert surveillance > Mobile recording > Video post-processing		Powered by QinetiQ Technology

StableEyes video stabilization system uses the very latest electronic image processing technology to reduce camera shake, leaving operators with clear and steady video. Installing StableEyes increases the effective operational range of high-zoom surveillance cameras where the slightest mechanical movement can introduce picture shake.

The StableEyes video stabilizer is simply installed in-line with the viewing monitor and is compatible with either live or pre-recorded video. The system operates by employing ultra-fast video motion analysis techniques to remove the shake in real-time, resulting in stable video, which is far easier to view. StableEyes can also improve the performance of digital compression systems, such as Internet or ISDN video links, as stable images compress more efficiently.

StableEyes is the result of a technology partnership agreement between QinetiQ and Ovation Systems. StableEyes image stabilization system draws on QinetiQ's vast experience of video imaging for defence applications coupled with Ovation's production engineering capability. It is the culmination of over 10 man-years of hardware and software development.

StableEyes Video Stabilizer Operation:

StableEyes image stabilisation operation.

StableEyes video stabilization system operates by locking onto detail within the incoming video to differentiate between shake and background. Once locked, StableEyes repositions each video frame to remove any shake resulting in clear and steady video. This is achieved by complex software algorithms running on the very latest multimedia hardware chip - the Philips Nexperia®. StableEyes has been specially developed to cope with demanding image stabilisation situations such as noisy video sources (eg low-light cameras), movement of large objects within the scene and operation with pan, tilt and zoom installations.

Video Stabiliser Installation

StableEyes is normally installed in-line with the viewing monitor with either a live camera feed or pre-recorded video. With CCTV systems, StableEyes is normally inserted in line with the operator’s spot monitor, as only the viewed camera requires stabilization. When not required, StableEyes may easily be by-passed by either switching off the unit, or via a remote switch / contact to ground.
