基于GAN的高光谱异常检测

GAN-based Hyperspectral Anomaly Detection

Sertac Arisoy, Nasser M. Nasrabadi, Koray Kayabol

摘要:

提出了一种基于生成对抗网络(GAN)的高光谱异常检测算法。在该算法中,我们训练一个GAN模型,以生成一个合成的背景图像,这是尽可能接近原始背景图像。通过从原始图像中减去合成图像,我们能够从高光谱图像中去除背景。通过在光谱差图像上应用Reed-Xiaoli(RX)异常检测器(AD)来执行异常检测。在实验部分,我们比较了我们提出的方法与经典的RX,加权RX(WRX)和支持向量数据描述(SVDD)的异常检测器和深度自动编码器异常检测(DAEAD)方法合成和真实的高光谱图像。检测结果表明,我们提出的算法优于其他方法在基准测试。

英文摘要:

In this paper, we propose a generative adversarial network (GAN)-based hyperspectral anomaly detection algorithm. In the proposed algorithm, we train a GAN model to generate a synthetic background image which is close to the original background image as much as possible. By subtracting the synthetic image from the original one, we are able to remove the background from the hyperspectral image. Anomaly detection is performed by applying Reed-Xiaoli (RX) anomaly detector (AD) on the spectral difference image. In the experimental part, we compare our proposed method with the classical RX, Weighted-RX (WRX) and support vector data description (SVDD)-based anomaly detectors and deep autoencoder anomaly detection (DAEAD) method on synthetic and real hyperspectral images. The detection results show that our proposed algorithm outperforms the other methods in the benchmark.
