摘要:

在遥感中,获取或收集准确标记的大型数据集通常具有挑战性。这种困难通常是由于几个问题,包括但不限于研究地点的空间面积和可访问性,全球定位系统(GPS)的错误,以及图像的空间分辨率造成的混合像素。我们提出了一种方法,有两个变化,估计多个目标签名的训练样本不精确的标签:多目标多实例自适应余弦估计(多目标MI-ACE)和多目标多实例光谱匹配滤波器(多目标MI-SMF)。所提出的方法通过直接考虑多实例、不精确标记的数据集来解决上述问题。他们学习目标特征的字典,使用自适应余弦估计(ACE)和光谱匹配滤波器(SMF)优化对背景的检测。实验进行了测试所提出的算法,使用模拟的高光谱数据集,MUUFL海湾港高光谱数据集收集的南密西西比大学海湾公园校区,和AVIRIS高光谱数据集收集的圣巴巴拉县,加利福尼亚州。仿真和实际高光谱目标检测实验表明,该算法在目标特征学习和目标检测方面是有效的。

英文摘要:

In remote sensing, it is often challenging to acquire or collect a large dataset that is accurately labeled. This difficulty is usually due to several issues, including but not limited to the study site's spatial area and accessibility, errors in the global positioning system (GPS), and mixed pixels caused by an image's spatial resolution. We propose an approach, with two variations, that estimates multiple target signatures from training samples with imprecise labels: Multi-Target Multiple Instance Adaptive Cosine Estimator (Multi-Target MI-ACE) and Multi-Target Multiple Instance Spectral Match Filter (Multi-Target MI-SMF). The proposed methods address the problems above by directly considering the multiple-instance, imprecisely labeled dataset. They learn a dictionary of target signatures that optimizes detection against a background using the Adaptive Cosine Estimator (ACE) and Spectral Match Filter (SMF). Experiments were conducted to test the proposed algorithms using a simulated hyperspectral dataset, the MUUFL Gulfport hyperspectral dataset collected over the University of Southern Mississippi-Gulfpark Campus, and the AVIRIS hyperspectral dataset collected over Santa Barbara County, California. Both simulated and real hyperspectral target detection experiments show the proposed algorithms are effective at learning target signatures and performing target detection.
