由于红外图像本身对比度和清晰度都较低，再加上海天场景的复杂多变，极大增加了海天背景下的红外舰船目标检测难度。为实现对多种复杂海天背景下的红外舰船的有效检测，提出了一种新的基于局部边缘梯度特性的舰船目标检测算法。对多种红外复杂海天场景图像进行仿真测试，实验结果表明：该算法能有效地检测出多种复杂海天背景下的红外舰船目标，适应性广，计算简便。

Low contrast of infrared images and complicated sea-sky scene greatly increased the difficulty of infrared warship target detection with complicated sea-sky background. In order to detect infrared warship under various complicated sea-sky background effectively, this paper presents a new algorithm based on local edge gradient. Carry out simulation testing by multi infrared complex sea-sky background image. Experimental results indicated that this algorithm can extract the warship under various complicated sea-sky background effectively, has good adaptation, and easy calculate.
