基于视觉显著性的RX舰船目标检测
|
摘要
为了有效检测出海杂波明显情况下的舰船目标,提出了一种基于视觉显著性的目标检测算子。该算法在传统异常检测算子中引入了视觉显著性算法,引入视觉显著性算法可有效抑制背景像素,加强目标像素。实验结果表明,该算法在海况复杂的情况下,能有效检测出舰船目标,降低虚警率。
In this paper,a saliency-based visual of RX algorithms for optical satellite images is proposed in order to detect ship target accurately when sea clutter has a big influence.Visual saliency could repress surround pixels and enhance target pixels.The experimence results indicate that the method can detect ship target in complex scene precisely and reduce false alarm rate.
