1476504 Frequency selective reflecting/refracting system HUGHES AIRCRAFT CO 12 June 1974 [25 June 1973] 26149/74 Heading G2J [Also in Division H4] An optical arrangement for a target tracking system, see group H4, includes a selectively reflecting surface carried on one surface of a separating...
The unit allows the target object to be aimed at and allows its angular deviation with respect to the line of sight to be determined by means of a single optical system, as a result of which adjustment devices are rendered superfluous. <IMAGE> 展开 ...
Object Detecting and Tracking Algorithm Based on Optical Flow Harris corner points were adopted as tracking objects,and scale space was introduced into corner point detection in order to extract Harris corner points in feature scale. Then curvature was computed to filter out false corners and enhan...

Motion tracking in persistent surveillance applications enters an interesting regime when the movers are of a size on the order of the image resolution elements or smaller. In this case, for reasonable scenes, information about the movers is a natively sparse signal - in an observation of a scen...
The results show a performance of the same order of magnitude as compared to some model based visual servo control research. Certain limitations to the algorithm are also discussed 展开 关键词: feedback filtering theory least squares approximations optical tracking parameter estimation prediction theory ...
and then used the IMM algorithm basing UKF to keep the tracking of the emitter.By using this method,the precision of the tracking filter can be improved,and it is also good to the filter's stability.The simulations proved the feasibility and availability of the new method.At last,further ...
Multitarget Bayes filtering via first-order multitarget moments The theoretically optimal approach to multisensor-multitarget detection, tracking, and identification is a suitable generalization of the recursive Bayes n...

To evaluate dynamic postural control, the Body Tracking Test (BTT) was developed. This paper investigated the optical target speed. The subject standing on the stabilometer was asked to track a moving optical target displayed on the screen by his/her bodily movement. Stabilometric data were recor...
