<title>Correspondence using property coherence</title>

Abstract

This paper presents a generalization of the correspondence approach of Sethi and Jam [13] by extending the path coherence criterion to high dimensional vector space. This allows the same correspondence procedure to be used for a variety of tokens including points, lines, planes, and regions. To demonstrate the generalized approach, we apply it to track lines and present experimental results.

“…Path coherence implies the smooth changing of motion speed and direction. The path coherence technique was later generalized to property coherence by Sethi et al [23]. They gave an example of tracking line segment tokens based on the coherence of a ®ve-dimensional property space with midpoint coordinates (x m ; y m ) of the line, line length r, line orientation h, and the directed distance of the line token from the image origin, d, as the token attributes.…”
