Research on Ship Target Recognition in Optical Remote Sensing Image Based on Local Feature Matching

In modern naval warfare, ship target is an important combat force on the battlefield of naval warfare. Different types of ship target have differences in combat mode and combat positioning. In order to accurately grasp the enemy combat ship movement, accurately analyze the enemy combat intention and firepower coverage in the naval battle field, the accurate identification of the ship target becomes a key problem. In this paper, a ship target type recognition method based on SIFT feature and Harris corner feature matching is proposed in view of the close size and similar appearance of different types of ship targets.
