Tracking filter algorithm for automatic video tracking
SPIE Proceedings, 2006In addition to servo control and power amplification, motion control systems for optical tracking pedestals feature capabilities such as electro-optical tracking using an integrated Automatic Video Tracker (AVT) card. An electro-optical system tracking loop is comprised of sensors mounted on a pointing pedestal, an AVT that detects a target in the ...

Proceedings of the 17th annual ACM symposium on User interface software and technology, 2004
This paper presents an approach for tracking paper documents on the desk over time and automatically linking them to the corresponding electronic documents using an overhead video camera. We demonstrate our system in the context of two scenarios, paper tracking and photo sorting.

2017 IEEE Third International Conference on Multimedia Big Data (BigMM), 2017
In this paper, we aim to identify and track people in a given video footage. We perform face detection and recognition, and then use a block matching algorithm to continuously track each detected face. We develop a simple, intuitive, user-friendly interface that enables search by name or image that is useful and convenient for people identification and

Tracking Consistency Metric for Video Surveillance Tracking
2009 International Conference on Signal Processing Systems, 2009The aim of this paper is to propose an additional performance tracking metric. The performance of a tracking algorithm depends on the parameters that are being tracked ranging from reference points that cover edges and corners, to blob parameters such as size, trajectory and color.

A Real-Time Video Tracking System
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980Object identification and tracking applications of pattern recognition at video rates is a problem of wide interest, with previous attempts limited to very simple threshold or correlation (restricted window) methods. New high-speed algorithms together with fast digital hardware have produced a system for missile and aircraft identification and tracking

Optical video disks with undulating tracks
Applied Optics, 1978The signal components of a video signal (luminance, color, and sound) are modulated on a main carrier and several subcarriers and then recorded on the video master disk. Apart from the signal distortion that can arise during master and disk manufacture, the optical readout of the disk also yields a nonlinear transfer of the signal.

Robust Multitask Multiview Tracking in Videos
IEEE Transactions on Neural Networks and Learning Systems, 2015Various sparse-representation-based methods have been proposed to solve tracking problems, and most of them employ least squares (LSs) criteria to learn the sparse representation. In many tracking scenarios, traditional LS-based methods may not perform well owing to the presence of heavy-tailed noise. In this paper, we present a tracking approach using
