Visual tracking has been a challenging problem in computer vision over the decades. The applications of visual tracking are far-reaching, ranging from surveillance and monitoring to smart rooms. Mean-shift tracker, which gained attention recently, is known for tracking objects in a cluttered environment. In this work, we propose a new method to track objects by combining two well-known trackers...

In the paper hereby, some issues related to training, evaluation, and selection of UAV operators are considered. particular, training process is carried out by means simulator C-STAR, SimLat Ltd group trainees. Each trainee told put a mobile eye tracker on, required perform exercises at pilot payload station and, eventually, take test. this way, trainees’ abilities estimated eligible candidates...

In this paper, a novel observer-based digital redesign tracker is proposed to resolve the output tracking problem for nonlinear sampled data systems. Acquiring parameters via a hybrid design of EP-based iterative learning control (EP-ILC) and linear quadratic analog tracker (LQAT), the tracker possesses good tracking performance both in transient state response and in steady state response when...

Ultra–relativistic heavy–ions carry strong electromagnetic and nuclear fields. Interactions between these fields in peripheral nucleus–nucleus collisions can probe many interesting physics topics. This presentation will focus on coherent two–photon and photonuclear processes at RHIC. The rates for these interactions will be high. The coherent coupling of all the protons in the nucleus enhances ...

We present the analyses of single electrons from semileptonic bottom and charm hadron decays at mid-rapidity in sNN=200and54.4GeV Au+Au collisions (talk Heavy-Flavor session III). The data sNN=200GeV incorporate information Heavy Flavor Tracker which enables topological separation originating decays. report first STAR measurements ν2 for decay as a function pT ν1 electron rapidity. Additionally...

A user often needs training and guidance while performing several daily life procedures, e.g., cooking, setting up a new appliance, or doing COVID test. Watch-based human activity recognition (HAR) can track users' actions during these procedures. However, out of the box, state-of-the-art HAR struggles from noisy data less-expressive that are part tasks. This paper proposes PrISM-Tracker, proce...

An efficient Kalman filter based algorithm has been proposed for the spacecraft attitude estimation problem using a novel split-field-of-view star camera and three-axis rate gyros. The conventional spacecraft attitude algorithm has been modified for on-orbit estimation of interlock angles between the two fields of view of star camera, gyro axis, and the spacecraft body frame. Real time estimati...
