Abstract The centerline as a distinct feature in ship ISAR image, its precision affects the recognition result. In this paper, a new ship centerline extraction algorithm is presented. According to this algorithm, the ship width and centerline are together detected by line group, and the parameters are optimized according to the radius and angle sensitivity of ship area in the line group. The simulation results demonstrate that this algorithm has higher precision, can adapt to images with different projection plane.
