光学遥感图像舰船目标检测算法研究

Study of target detection algorithm based on optical remote sensing images

针对航天图像舰船目标快速检测问题,本文提出了一种复杂海洋背景中舰船目标的快速提取,舰船尾迹的检测及目标检测算法。根据人类视觉注意机制,把梯度作为视觉注意前期的简单特征,然后以开尔文尾迹为主要依据,以区域灰度方差表示纹理粗糙度,进行舰船尾迹识别,最后分析舰船检测的原则和主要特征,提出舰船目标检测流程,并进行目标检测实验,实现准确的尾迹识别和目标检测。

Rapid detection problem for a space ship image target,this paper proposes a rapid extraction of ship target in the complex background of marine,ship wake detection and target detection algorithm. According to human visual attention mechanism,the gradient as a simple features of visual attention early,then kelvin wake as the main basis,expressed as a regional gray variance texture roughness,is used to identify the ship wake,finally analyzes the principle and main characteristics of ship detection,put forward the ship target detection process,and the target detection experiment,has realized the accurate trail identify and target detection.
