Video Trackers

North Star's engineers have a long history of video tracker work, having been the autotracker developers for the Army's Fiber Optic Guided Missile (FOG-M) program (1984-1999) and performing key roles in the development of the autotracker/cuer for the Navy's Phalanx Close-in Weapon System (1994-1997).  We have designed both the hardware and software for many tracking applications including terminal guidance, cueing, automatic target acquisition, gimbal line-of-sight stabilization, scene-tracking to stabilize an image on the background, and motion detection.  Our autotrackers and related algorithms are designed to run real-time, and to operate in a closed-loop control environment with sensors and weapons.

	Embedded Video Tracker Our Embedded Video Tracker (EVT) is a complete small-format PC/104 autotracker.  Using state-of-the-art high-density gate arrays and Motorola's Power PC processor, the EVT utilizes the AT-bus to communicate with a host Intel x86 processor.  We are using the Pentium family of processors to host the EVT.  The analog video inputs support two channels of either TV or IR video in the industry standard RS-170 and NTSC formats.

Bomb Drop Segmentation and Tracking

Our Bomb Drop segmentation and tracking algorithms were developed to post-process weapon test videos at Nellis AFB.  These algorithms can be used to collect exact weapon position data with little or no operator intervention.

Autodetector

North Star's Autodetector was developed for low-cost, small-size, security camera surveillance applications.  These algorithms detect motion in an otherwise fixed scene, and alert security personnel to take a closer look or to automatically record the video.  The application was developed in C++, and is hosted on a standard PC.
