A new algorithm for ship centerline extraction in ISAR image
Linlin Du, Xin Yu-lin, Zengping Chen · 2010
The centerline is an important feature in ISAR image features. In this paper, a new ship centerline extraction algorithm is presented. In the improved algorithm, the width character is used in the extraction of the ship centerline, and the line detection in normal centerline detection methods is replaced by line group detection. After finding the ship width and angle, the centerline position can be defined. The simulation results show that the estimation of ship centerline with this algorithm can reach higher precision than that of least-squares method and the projection method.
