| 摘 要： | 提出一种基于分布异常的高光谱遥感影像小目标检测方法。该算法用基于近似相对熵的实码遗传优化投影寻踪方法(RCGOA-PP),有效地将高维数据中隐藏的目标信息集中投影到低维空间中,并用直方图分割的方法提取出小目标。实验证明,此算法精度较高,适用于对高光谱影像中的小目标进行检测。

| Abstract: | This paper presents a small targets detection approach based on anomaly distributing in hyperspectral data.This algorithm uses approximate entropy index's Projection Pursuit based on Real Coding Genetic Optimize Algorithm(RCGOAPP) to project the targets information hided in the high-dimensional data into low-dimensional space and then extract small targets with histogram image segmentation method.It is proved that this algorithm adapts to detect small targets in simple or complicated scene and has an excellent precision result. |
