Contour analysis application for object detection in aerial image sequence

Abstract

The object detection problems in the aerial image sequence for the aircraft navigation task are considered; the brief review of the methods which are traditionally used in the considered field is represented; the aerial image sequence processing and analysis technique on the basis of the developed contour analysis algorithms for the object detection in the analyzed aerial images is suggested; the way to apply the developed contour analysis algorithms to solve the assigned task is indicated; some of these algorithms are considered in detail, viz. the approximating polygon finding algorithm, the subcontour generation algorithm, the corresponding points direct selection algorithm; the experimental results of the developed algorithms for the test aerial image sequence are shown; the possible direction for the future research is mentioned.
