Showing papers on "Motion analysis published in 1978"
TL;DR: In this article, the problem of performing target motion analysis using noisy bearing measurements derived from multiple observation platforms or from a single moving observer is addressed, and the properties of an estimator based on a Cartesian model of the process are detailed.
Abstract: The problem of performing target motion analysis using noisy bearing measurements derived from multiple observation platforms or from a single moving observer is addressed. For the latter case, the properties of an estimator based on a Cartesian model of the process are detailed. Methods of providing estimates both before an observer maneuver, when the process is unobservable, and following an observer maneuver are developed. The results of an experimental study are presented.

TL;DR: This paper presents a number of interesting applications which have been made successful through the use of a digital camera with computer control of the X-Y scanning of the image.
Abstract: A large part of computing is involved with transferring data in and out of the computer interface. Vast amounts of information are traditionally stored or designed to be interpreted visually by human operators. This information must be made acceptable to the computer by either coding it for binary input or by giving the computer a visual input device. A digitally controlled image detector is one approach to this problem. This paper presents a number of interesting applications which have been made successful through the use of a digital camera with computer control of the X-Y scanning of the image.
